1 Introduction Instrument and Operation

Instrument and Operation

Introduction to the Pump The binary pump comprises two identical pumps integrated into one housing. Binary gradients are created by high-pressure mixing. A built-in degasser is available for applications that require best flow stability, especially at low flow rates, for maximum detector sensitivity. Pulse damper and mixer can be bypassed for low flowrate applications or whenever a minimal transient volume is desirable. Typical applications are high throughput methods with fast gradients on high resolution 2.1 mm columns. The pump is capable of delivering flow in the range of 0.1 5 mL/min against up to 600 bar. A solvent selection valve (optional) allows to form binary mixtures (isocratic or gradient) from one of two solvents per channel. Active seal wash (optional) is available for use with concentrated buffer solutions.

Figure 1 Overview of the binary pump

InfinityLab LC Series 1260 Infinity II Binary Pump User Manual 11

1 Introduction Instrument and Operation

Principle of Operation The binary pump is based on a two-channel, dual-piston in-series design which comprises all essential functions that a solvent delivery system has to fulfill. Metering of solvent and delivery to the high-pressure side are performed by two pump assemblies which can generate pressure up to 600 bar.

Each channel comprises a pump assembly including pump drive, pump head, active inlet valve with replaceable cartridge, and outlet valve. The two channels are fed into a low-volume mixing chamber which is connected via a restriction capillary coil to a damping unit and a mixer. A pressure sensor monitors the pump pressure. A purge valve with integrated PTFE frit is fitted to the pump outlet for convenient priming of the pumping system.

1 Introduction Overview of the Hydraulic Path

Overview of the Hydraulic Path

The solvent from the bottle in the solvent cabinet enters the pump through an active inlet valve. Each side of the binary pump comprises two substantially identical pump units. Both pump units comprise a ball-screw drive and a pump head with two sapphire pistons for reciprocating movement.

Figure 5 Pump head

A servo-controlled variable reluctance motor drives the two ball-screw drives in opposite directions. The gears for the ball-screw drives have different circumferences (ratio 2:1) allowing the first piston to move at double the speed of the second piston. The solvent enters the pump heads close to the bottom limit and leaves it at its top. The outer diameter of the piston is smaller than the inner diameter of the pump-head chamber allowing the solvent to fill the gap in between. The first piston has a stroke volume in the range of 20 L to 100 L depending on the flow rate. The microprocessor controls all flow rates in a range

of 1 L/min to 5 mL/min. The inlet of the first pumping unit is connected to the active inlet valve which is processor-controlled opened or closed allowing solvent to be drawn into the first pump unit.

The outlet of the first pump chamber is connected by a 500 L absorber capillary to the second pump chamber. The outlets of the second chambers of both pump channels joined via a small mixing chamber. A coiled restriction capillary connects the mixing chamber via a pressure pulse damper, a mixer and a pressure sensor to the purge valve assembly. The outlet of the purge valve assembly is then connected to the attached chromatographic system.

When turned on, the pump runs through an initialization procedure to determine the upper dead center of the first piston of both pump channels. The first piston moves slowly upwards to the mechanical stop of the pump head and from there it moves back a predetermined path length. The controller stores this piston position in memory. After this initialization the pump starts operation with the set parameters for the two pump channels.

The active inlet valve is opened and the down moving piston draws solvent into the first pump head. At the same time the second piston is moving upwards delivering into the system. After a controller defined stroke length (depending on the flow rate) the drive motors are stopped and the active inlet valve is closed. The motor direction is reversed and moves the first piston up until it reaches the stored upper limit and at the same time moving the second piston downwards.

Then the sequence starts again moving the pistons up and down between the two limits. During the delivery stroke of the first piston the solvent in the pump head is pressed through the outlet valve into the second pumping unit. The second piston draws in half of the volume displaced by the first piston and the remaining half volume is directly delivered into the system. During the drawing stroke of the first piston, the second piston delivers the drawn volume into the system.

For pump specifications, see Performance Specifications on page 30.

1 Introduction Overview of the Hydraulic Path

What is Pump Elasticity Compensation?

The flow path of the pump consists of pump chambers, sapphire pistons, polymer seals, stainless steel tubing of different dimension, pressure sensor, and so forth. All of these parts deform when pressurized. The sum of this deformation is called pump elasticity.

Let us look at a practical example: Piston 1 draws solvent at ambient pressure. The movement direction is reversed and the piston 1 now compresses the solvent until the operating pressure of the HPLC system is reached. The outlet valve opens, and solvent is pumped by piston 1 into pump chamber 2. Due to two factors, the solvent volume that is delivered into the system at high pressure is smaller than it is supposed to be:

1 The solvent is compressible

2 The pump has a certain elasticity which causes its internal volume to increase with pressure.

In order to compensate for these two influences, their contributions must be known. An elasticity calibration allows separating pump properties from solvent properties and therefore allows transferring solvent properties, which have been obtained from one pump to another pump with different elasticity.

Elasticity calibration is done with a solvent, which properties (compressibility, thermal expansion) are well-known and documented: pure water. When pumping water and using its property data for controlling the pump, any deviations from the theoretical pressure profile during solvent recompression are caused by the elasticity of the pump.

The Pump Elasticity Calibration calculates correction factors to compensate for the individual elasticity of the pump that is being calibrated. The elasticity is different for every pump and may change with the replacement of parts in the flow path, e.g. pump seals.

All binary pumps are elasticity calibrated at the factory and require recalibration only after preventive maintenance or major repairs to the flow path. Replacement of capillaries or PTFE frits are not considered as a major repair.

CAUTION Incorrect pump elasticity calibration.

Solvent compressibility calibrations acquired with a miscalibrated pump will work, but they are not transferable to other pumps. A correct pump elasticity calibration is an essential prerequisite for successful solvent compressibility calibrations.

Calibrate the pump elasticity correctly.

InfinityLab LC Series 1260 Infinity II Binary Pump User Manual 17

1 Introduction Overview of the Hydraulic Path

What is Solvent Compressibility Compensation?

Although the compressibility of liquids is orders of magnitude lower than the compressibility of gases, without correction a noticeable volume error would be seen if typical chromatographic solvents are compressed to operating pressures as high as 600 bar. In addition, the compressibility depends on pressure, temperature and the amount of dissolved gas. In order to minimize the influence of the latter, the use of a vacuum degasser is mandatory for a high flow and composition precision. Unfortunately, the influence of the temperature on compressibility is non-linear and cannot be calculated.

The Agilent 1260 Infinity II Binary Pump features a multi point compressibility calibration. The compressibility of a solvent is determined at different pressures from 0 600 bar and stored in an XML file. This file can be distributed to other pumps because the solvent compressibility is independent from the pump.

The binary pump and ChemStation come with predetermined solvent compressibility data for the most common HPLC solvents like water, acetonitrile, methanol, etc. Users can calibrate their own solvent mixtures with the help of an easy to use calibration procedure in the Agilent Lab Advisor software.

Let us use the practical example from the last section once again to understand how compressibility compensation works:

Piston 1 draws solvent at ambient pressure. The movement direction is reversed and piston 1 now compresses the solvent until the operating pressure of the HPLC system is reached. The outlet valve opens, and solvent is pumped by piston 1 into pump chamber 2.

Without any compensation, the delivered volume at operating pressure would be too low. In addition, it would take a noticeable amount of time to recompress the solvent to operating pressure. During this time frame, no solvent would be delivered into the system and as a result a high pressure fluctuation (known as pressure ripple) would be observed.

When both solvent compressibility at the current operating pressure and pump elasticity are known, the pump can automatically correct for the missing volume by drawing the appropriate larger solvent volume at ambient pressure and speed up the piston during the recompression phase in the first pump chamber. As a result, the pump delivers the accurate volume with any (calibrated) solvent at any pressure at a greatly reduced pressure ripple. For applications that require lowest transition volume of the pump, damper and mixer can be bypassed.

For compatibility with older methods from G1312A Binary Pumps, the previous one-point compressibility compensation is available, too. However, since the compressibility is a non-linear function, one single compressibility value per solvent will only give good results at one particular pressure.

InfinityLab LC Series 1260 Infinity II Binary Pump User Manual 18

1 Introduction Overview of the Hydraulic Path

How Does Variable Stroke Volume Work?

The smaller the solvent volume in the pump chamber is, the faster it can be recompressed to operating pressure. The binary pump allows to manually or automatically adjust the pump stroke volume of the first piston in the range of 20 100 L. Due to the compression of the solvent volume in the first pump chamber, each piston stroke of the pump will generate a small pressure pulsation, influencing the flow ripple of the pump. The amplitude of the pressure pulsation mainly depends on the stroke volume and the compressibility compensation for the solvent in use. Small stroke volumes generate less pressure pulsation than larger stroke volumes at the same flow rate. In addition, the frequency of the pressure pulsation will be higher. This will decrease the influence of flow pulsations on retention times.

In gradient mode, a smaller stroke volume results in less flow ripple and reduces the composition ripple.

The binary pump uses a processor-controlled ball screw system for driving its pistons. The normal stroke volume is optimized for the selected flow rate. Small flow rates use a small stroke volume while higher flow rates use a higher stroke volume.

The stroke volume for the pump is by default set to AUTO mode. This means that the stroke is optimized for the flow rate in use. A change to larger stroke volumes is possible but not recommended.

1 Introduction Leak and Waste Handling

Leak and Waste Handling

The Agilent InfinityLab LC Series has been designed for safe leak and waste handling. It is important that all security concepts are understood and instructions are carefully followed.

The solvent cabinet is designed to store a maximum volume of 8 L solvent. The maximum volume for an individual bottle stored in the solvent cabinet should not exceed 2 L. For details, see the usage guideline for the Agilent Infinity II Solvent Cabinets (a printed copy of the guideline has been shipped with the solvent cabinet, electronic copies are available on the Internet).

All leak plane outlets are situated in a consistent position so that all Infinity and Infinity II modules can be stacked on top of each other. Waste tubes are guided through a channel on the right hand side of the instrument, keeping the front access clear from tubes.

The leak plane provides leak management by catching all internal liquid leaks, guiding them to the leak sensor for leak detection, and passing them on to the next module below, if the leak sensor fails. The leak sensor in the leak plane stops the running system as soon as the leak detection level is reached.

Solvent and condensate is guided through the waste channel into the waste container:

from the detector's flow cell outlet

from the Multisampler needle wash port

from the Sample Cooler or Sample Thermostat (condensate)

from the pump's Seal Wash Sensor (if applicable)

from the pump's Purge Valve or Multipurpose Valve

3 Using the Pump Best Practices

Best Practices

Daily / Weekly tasks

Daily tasks

Replace mobile phase based on water/buffer.

Replace organic mobile phase latest every second day.

Check seal wash solvent.

Weekly Tasks

Change seal wash solvent (10 % isopropanol in water) and bottle.

If applications with salts were used, flush all channels with water and remove possible salt deposits manually.

Inspect solvent filters for dirt or blockages. Exchange if no flow is coming out of the solvent line when removed from the degasser inlet.

Power up / Shut-down the pump

Power up the pump

Use new or different mobile phase (as required).

3 Using the Pump Best Practices

Prepare the pump

Purge

Use the Purge function to:

fill the pump,

exchange a solvent,

remove air bubbles in tubes and pump heads.

Seal wash

Seal Wash guarantees a maximum seal life time. Use Seal Wash:

When using buffers with elevated salt concentrations

When using volatile solvents with non-volatile additives

How to deal with solvents Use clean bottles only.

Exchange water-based solvents daily.

Select solvent volume to be used up within 1 2 days.

Use only HPLC-grade solvents and water filtered through 0.2 m filters.

Label bottles correctly with bottle content, and filling date / expiry date.

Use solvent inlet filters.

Reduce risk of algae growth: use brown bottles for aqueous solvents, avoid direct sunlight.

CAUTION Contaminated seal wash solvent

Do not recycle seal wash solvent to avoid contamination.

Weekly exchange seal wash solvent.

3 Using the Pump Leak and Waste Handling

Leak and Waste Handling

For details on correct installation, see separate installation documentation.

WARNING Toxic, flammable and hazardous solvents, samples and reagents

The handling of solvents, samples and reagents can hold health and safety risks.

When working with these substances observe appropriate safety procedures (for example by wearing goggles, safety gloves and protective clothing) as described in the material handling and safety data sheet supplied by the vendor, and follow good laboratory practice.

Do not use solvents with an auto-ignition temperature below 200 C (392 F). Do not use solvents with a boiling point below 56 C (133 F).

Avoid high vapor concentrations. Keep the solvent temperature at least 40 C (72 F) below the boiling point of the solvent used. This includes the solvent temperature in the sample compartment. For the solvents methanol and ethanol keep the solvent temperature at least 25 C (45 F) below the boiling point.

Do not operate the instrument in an explosive atmosphere.

Do not use solvents of ignition Class IIC according IEC 60079-20-1 (for example, carbon disulfide).

Reduce the volume of substances to the minimum required for the analysis.

Never exceed the maximum permissible volume of solvents (8 L) in the solvent cabinet. Do not use bottles that exceed the maximum permissible volume as specified in the usage guideline for solvent cabinet.

Ground the waste container.

Regularly check the filling level of the waste container. The residual free volume in the waste container must be large enough to collect the waste liquid.

To achieve maximal safety, regularly check the tubing for correct installation.

NOTE For details, see the usage guideline for the solvent cabinet. A printed copy of the guideline has been shipped with the solvent cabinet, electronic copies are available in the Agilent Information Center or via the Internet.

InfinityLab LC Series 1260 Infinity II Binary Pump User Manual 39

3 Using the Pump Hints for Successful Use of the Binary Pump

Hints for Successful Use of the Binary Pump

Place solvent cabinet with the solvent bottles always on top (or at a higher level) of the pump.

Flush the degasser with at least 5 mL per channel before operating the pump, especially when the pumping system had been turned off for a certain length of time (for example, overnight) and volatile solvent mixtures are used in the channels.

Prevent blocking of solvent inlet filters (never use the pump without solvent inlet filters). Growth of algae should be avoided (see Prevent Blocking of Solvent Filters on page 55).

Check purge valve frit and column frit in regular time intervals. A blocked purge valve frit can be identified by black, yellow or greenish layers on its surface or by a pressure greater than 10 bar in low delay volume configuration and 20 bar in standard configuration when pumping distilled water at a rate of 5 mL/min with an open purge valve.

Whenever possible use a minimum flow rate of 5 L/min per solvent channel to avoid crossflow of solvent into the unused pump channel.

Whenever exchanging the pump seals, the purge valve frit should be exchanged, too.

When using buffer solutions, flush the system with water before switching it off. The seal wash option should be used when installed, especially when buffer solutions with concentrations of 0.1 M or higher are being pumped for long periods of time.

Check the pump pistons for scratches, grooves and dents when changing the piston seals. Damaged pistons cause micro leaks and will decrease the lifetime of the seals.

After changing the piston seals, apply the seal wear-in procedure (see Seal Wear-in Procedure on page 133).

Place the aqueous solvent on channel A and the organic solvent on channel B. The default compressibility settings are set accordingly.

Setting up the Pump with the G4208A Instant Pilot

Generic operation of the G4208A Instant Pilot is covered in the Agilent Instant Pilot G4208A User's Guide (G4208-90006). Details about setting up module specific parameters can be found in the Instant Pilot online help.

The pump parameters are described in detail in Overview on page 42.

Setting up the Pump with the Instrument Control Interface

Overview Parameters described in following sections are offered by the instrument control interface and can usually be accessed through Agilent instrument control software. For details, please refer to manuals and online help of respective user interfaces.

InfinityLab LC Series 1260 Infinity II Binary Pump User Manual 42

3 Using the Pump Setting up the Pump with the Instrument Control Interface

Setup of Basic Pump Parameters The most important parameters of the pump are listed in Table 3 on page 43.

Table 3 Basic pump parameters

Parameter Limits Description

Flow 0.001 5 mL/min Total flow rate of the pump. See When to Remove Damper and Mixer on page 63 for pump hardware modifications to achieve lowest delay volume.

Stop Time 0.01 min - no limit The stop time of the pump usually controls the run time of the whole LC system. Use no limit to stop the run manually (useful for method development).

Post Time off - 99999 min Time between the end of a run and the start of the next. Used for column equilibration after a gradient.

Pressure Limits

Max: 0 600 bar Min: 0 600 bar

Max must be bigger than Min! Set max pressure to the maximum operating pressure of your column. A min pressure setting of e.g. 10 bar will turn off your pump automatically when running out of solvent. A smarter way, however, is to use the bottle fillings function (see Bottle Filling on page 46).

Solvent A 0 100 % Although channel A can be set to 0 %, it cannot be turned off. This channel should be used for the aqueous phase (water).

Solvent B off - 100 % The percentage of channel B is automatically complemented by channel A to give 100 %.

Solvent type

H2O, ACN, MeOH, IPA Select the solvent you are using in the respective solvent channel from the drop-down list. In case your solvent is not listed, perform a solvent compressibility calibration (see Running the Solvent Compressibility Calibration on page 101). For details on solvent compressibility see Binary Pump Solvent Compressibility Calibration on page 100.

Solvent Comment

Free text field for a description of the solvent. This description will show up in method printouts, etc.

Timetable max. number of lines depends on free space in pump memory

Use the timetable to build solvent gradients, flow gradients, or combinations of both. Gradients are always linear. Use multiple timetable entries to mimic exponential or parabolic gradients.

Display There are three ways to display the timetable: in tabular form as flow/pressure graph as solvent percentage plot Values can only be changed in tabular view.

InfinityLab LC Series 1260 Infinity II Binary Pump User Manual 43

3 Using the Pump Setting up the Pump with the Instrument Control Interface

Pump Control The pump can be switched between following states: On, Off or to Standby. In Standby, the pump motor is still controlled. When the pump is switched on from standby, it does not re-initialize.

The optional seal wash pump can be controlled by either switching it off, using it for a single time or specifying frequency and duration of periodic wash intervals.

Auxiliary Pump Parameters The auxiliary pump parameters are pre-set to fit most applications. Adjustments should only be made when required. Table 4 on page 45 shows the available auxiliary parameters with their default values.

CAUTION Upon initialization, the pump ignores the Maximum Flow Gradient value.

This can result in a rapid and uncontrolled pressure increase.

To prevent harm to the column, open the purge valve until the initialization is finished.

Data Curves The binary pump provides the possibility to store the following operational data in the data file of the Agilent data system:

Solvent percentage for each channel,

pump flow,

pressure

For details, please refer to the online help or manual of your instrument control software.

Table 4 Auxiliary pump parameters

Parameter Limits Description

Maximum Flow Gradient

0.1 100 mL/min default: 100 mL/min

With this parameter flow rate changes can be ramped up and down slowly to avoid pressure shocks to the column. The default value is 100 mL/min which in fact turns the function off.

Minimum Stroke 20 100 L default: Auto

The volume one pump piston delivers per stroke. In general, a smaller stroke volume results in lower pump ripple. The Auto setting adjusts the strokes dynamically to the lowest possible value. The strokes can be set individually for pump heads A and B.

Compressibility 0 - 15010-6 /bar or enhanced compressibility calibration default: use enhanced comp. calibration

For best performance, check option Use enhanced compressibility calibration. With this option, the pump will use solvent data libraries provided by Agilent or data generated by using solvent compressibility calibrations (see Running the Solvent Compressibility Calibration on page 101). For details on solvent compressibility see Binary Pump Solvent Compressibility Calibration on page 100. For backward compatibility to 400 bar pumps, the solvent compressibility can still be set manually for each channel when the box is unticked.

NOTE The pressure data curve is generated from the pressure sensor readings, while %A, %B and flow are calculated from the method settings of the pump.

InfinityLab LC Series 1260 Infinity II Binary Pump User Manual 45

3 Using the Pump Setting up the Pump with the Instrument Control Interface

Bottle Filling The pump offers a powerful feature to monitor the liquid level in the solvent bottles. With total bottle volume and initial filling volume set correctly, the pump subtracts the consumed volume continuously from the initial value and stops the pump and method/sequence execution before the system runs dry or an analysis is corrupted.

Table 5 on page 46 lists the available bottle filling parameters.

CAUTION The bottle filling feature fails if multiple solvent inlets are put into one solvent bottle!

In that case implement a minimum pressure limit to avoid that the pump runs dry when solvents are empty.

Table 5 Bottle Filling Parameters

Parameter Limits Description

Total Volume 0 1000 L default: 0 L

This is the capacity (maximum possible volume) in liter of the solvent bottle. In combination with the actual volume, this parameter is used for calculating and displaying the relative liquid level.

Actual Volume

0 1000 L default: 0 L

After filling the solvent bottles, enter the actual volumes into these boxes. The Actual Volume must not be larger than the Total Volume of the bottle.

Prevent analysis.......

default: unchecked If this option is checked, the pump wont start a new run if the solvent level in one or more bottles is below the minimum volume. Enter a minimum volume in liter, which considers the position of the solvent inlet and size/shape of the solvent bottle such that no air is drawn if the actual volume gets close to this limit.

Turn pump off...

default: unchecked If this option is checked, the pump will turn off before air is aspirated. However, the residual solvent volume has been calculated for 1 L solvent bottles and may be too small for large bottles or other vessels.

3 Using the Pump Solvent Information

Solvent Information

Observe the following recommendations on the use of solvents.

Follow the recommendations for avoiding the growth of algae, see Algae Growth in HPLC Systems on page 54

Small particles can permanently block capillaries and valves. Therefore, always filter solvents through 0.22 m filters.

Avoid or minimize the use of solvents that may corrode parts in the flow path. Consider specifications for the pH range given for different materials such as flow cells, valve materials etc. and recommendations in subsequent sections.

3 Using the Pump Solvent Information

General Information about Solvent/Material Compatibility Materials in the flow path are carefully selected based on Agilents experiences in developing highest-quality instruments for HPLC analysis over several decades. These materials exhibit excellent robustness under typical HPLC conditions. For any special condition, please consult the material information section or contact Agilent.

Disclaimer

Subsequent data was collected from external resources and is meant as a reference. Agilent cannot guarantee the correctness and completeness of such information. Data is based on compatibility libraries, which are not specific for estimating the long-term life time under specific but highly variable conditions of UHPLC systems, solvents, solvent mixtures and samples. Information can also not be generalized due to catalytic effects of impurities like metal ions, complexing agents, oxygen etc. Apart from pure chemical corrosion, other effects like electro corrosion, electrostatic charging (especially for non-conductive organic solvents), swelling of polymer parts etc. need to be considered. Most data available refers to room temperature (typically 20 25 C, 68 77 F). If corrosion is possible, it usually accelerates at higher temperatures. If in doubt, please consult technical literature on chemical compatibility of materials.

MP35N

MP35N is a nonmagnetic, nickel-cobalt-chromium-molybdenum alloy demonstrating excellent corrosion resistance (for example, against nitric and sulfuric acids, sodium hydroxide, and seawater) over a wide range of concentrations and temperatures. In addition, this alloy shows exceptional resistance to high-temperature oxidation. Due to excellent chemical resistance and toughness, the alloy is used in diverse applications: dental products, medical devices, nonmagnetic electrical components, chemical and food processing equipment, marine equipment. Treatment of MP35N alloy samples with 10 % NaCl in HCl (pH 2.0) does not reveal any detectable corrosion. MP35N also demonstrates excellent corrosion resistance in a humid environment. Although the influence of a broad variety of solvents and conditions has been tested, users should keep in mind that multiple factors can affect corrosion rates, such as temperature, concentration, pH, impurities, stress, surface finish, and dissimilar metal contacts.

InfinityLab LC Series 1260 Infinity II Binary Pump User Manual 48

3 Using the Pump Solvent Information

Polyphenylene Sulfide (PPS)

Polyphenylene sulfide has outstanding stability even at elevated temperatures. It is resistant to dilute solutions of most inorganic acids, but it can be attacked by some organic compounds and oxidizing reagents. Nonoxidizing inorganic acids, such as sulfuric acid and phosphoric acid, have little effect on polyphenylene sulfide, but at high concentrations and temperatures, they can still cause material damage. Nonoxidizing organic chemicals generally have little effect on polyphenylene sulfide stability, but amines, aromatic compounds, and halogenated compounds may cause some swelling and softening over extended periods of time at elevated temperatures. Strong oxidizing acids, such as nitric acid (> 0.1 %), hydrogen halides (> 0.1 %), peroxy acids (> 1 %), or chlorosulfuric acid degrade polyphenylene sulfide. It is not recommended to use polyphenylene sulfide with oxidizing material, such as sodium hypochlorite and hydrogen peroxide. However, under mild environmental conditions, at low concentrations and for short exposure times, polyphenylene sulfide can withstand these chemicals, for example, as ingredients of common disinfectant solutions.

PEEK

PEEK (Polyether-Ether Ketones) combines excellent properties regarding biocompatibility, chemical resistance, mechanical and thermal stability. PEEK is therefore the material of choice for UHPLC and biochemical instrumentation.

It is stable in the specified pH range (for the Bio-Inert LC system: pH 1 13, see bio-inert module manuals for details), and inert to many common solvents.

There is still a number of known incompatibilities with chemicals such as chloroform, methylene chloride, THF, DMSO, strong acids (nitric acid > 10 %, sulfuric acid > 10 %, sulfonic acids, trichloroacetic acid), halogens or aqueous halogen solutions, phenol and derivatives (cresols, salicylic acid, and so on).

When used above room temperature, PEEK is sensitive to bases and various organic solvents, which can cause it to swell. Under such conditions, normal PEEK capillaries are sensitive to high pressure. Therefore, Agilent uses stainless steel cladded PEEK capillaries in bio-inert systems. The use of stainless steel cladded PEEK capillaries keeps the flow path free of steel and ensures pressure stability up to 600 bar. If in doubt, consult the available literature about the chemical compatibility of PEEK.

InfinityLab LC Series 1260 Infinity II Binary Pump User Manual 49

3 Using the Pump Solvent Information

Polyimide

Agilent uses semi-crystalline polyimide for rotor seals in valves and needle seats in autosamplers. One supplier of polyimide is DuPont, which brands polyimide as Vespel, which is also used by Agilent.

Polyimide is stable in a pH range between 1 and 10 and in most organic solvents. It is incompatible with concentrated mineral acids (e.g. sulphuric acid), glacial acetic acid, DMSO and THF. It is also degraded by nucleophilic substances like ammonia (e.g. ammonium salts in basic conditions) or acetates.

Polyethylene (PE)

Agilent uses UHMW (ultra-high molecular weight)-PE/PTFE blends for yellow piston and wash seals, which are used in 1290 Infinity pumps, 1290 Infinity II pumps, the G7104C and for normal phase applications in 1260 Infinity pumps.

Polyethylene has a good stability for most common inorganic solvents including acids and bases in a pH range of 1 to 12.5. It is compatible with many organic solvents used in chromatographic systems like methanol, acetonitrile and isopropanol. It has limited stability with aliphatic, aromatic and halogenated hydrocarbons, THF, phenol and derivatives, concentrated acids and bases. For normal phase applications, the maximum pressure should be limited to 200 bar.

Tantalum (Ta)

Tantalum is inert to most common HPLC solvents and almost all acids except fluoric acid and acids with free sulfur trioxide. It can be corroded by strong bases (e.g. hydroxide solutions > 10 %, diethylamine). It is not recommended for the use with fluoric acid and fluorides.

InfinityLab LC Series 1260 Infinity II Binary Pump User Manual 50

3 Using the Pump Solvent Information

Stainless Steel (SST)

Stainless steel is inert against many common solvents. It is stable in the presence of acids and bases in a pH range of 1 to 12.5. It can be corroded by acids below pH 2.3. It can also corrode in following solvents:

Solutions of alkali halides, their respective acids (for example, lithium iodide, potassium chloride, and so on) and aqueous solutions of halogens.

High concentrations of inorganic acids like nitric acid, sulfuric acid and organic solvents especially at higher temperatures (replace, if your chromatography method allows, by phosphoric acid or phosphate buffer which are less corrosive against stainless steel).

Halogenated solvents or mixtures which form radicals and/or acids, for example:

2 CHCl3 + O2 2 COCl2 + 2 HCl

This reaction, in which stainless steel probably acts as a catalyst, occurs quickly with dried chloroform if the drying process removes the stabilizing alcohol.

Chromatographic grade ethers, which can contain peroxides (for example, THF, dioxane, diisopropylether). Such ethers should be filtered through dry aluminium oxide which adsorbs the peroxides.

Solutions of organic acids (acetic acid, formic acid, and so on) in organic solvents. For example, a 1 % solution of acetic acid in methanol will attack steel.

Solutions containing strong complexing agents (for example, EDTA, ethylene diamine tetra-acetic acid).

Mixtures of carbon tetrachloride with isopropanol or THF.

InfinityLab LC Series 1260 Infinity II Binary Pump User Manual 51

3 Using the Pump Solvent Information

Titanium (Ti)

Titanium is highly resistant to oxidizing acids (for example, nitric, perchloric and hypochlorous acid) over a wide range of concentrations and temperatures. This is due to a thin oxide layer on the surface, which is stabilized by oxidizing compounds. Non-oxidizing acids (for example, hydrochloric, sulfuric and phosphoric acid) can cause slight corrosion, which increases with acid concentration and temperature. For example, the corrosion rate with 3 % HCl (about pH 0.1) at room temperature is about 13 m/year. At room temperature, titanium is resistant to concentrations of about 5 % sulfuric acid (about pH 0.3). Addition of nitric acid to hydrochloric or sulfuric acids significantly reduces corrosion rates. Titanium is sensitive to acidic metal chlorides like FeCl3 or CuCl2. Titanium is subject to corrosion in anhydrous methanol, which can be avoided by adding a small amount of water (about 3 %). Slight corrosion is possible with ammonia > 10 %.

Diamond-Like Carbon (DLC)

Diamond-Like Carbon is inert to almost all common acids, bases and solvents. There are no documented incompatibilities for HPLC applications.

Fused silica and Quartz (SiO2)

Fused silica is used in Max Light Cartridges. Quartz is used for classical flow cell windows. It is inert against all common solvents and acids except hydrofluoric acid and acidic solvents containing fluorides. It is corroded by strong bases and should not be used above pH 12 at room temperature. The corrosion of flow cell windows can negatively affect measurement results. For a pH greater than 12, the use of flow cells with sapphire windows is recommended.

Gold

Gold is inert to all common HPLC solvents, acids and bases within the specified pH range. It can be corroded by complexing cyanides and concentrated acids like aqua regia.

Zirconium Oxide (ZrO2)

Zirconium Oxide is inert to almost all common acids, bases and solvents. There are no documented incompatibilities for HPLC applications.

InfinityLab LC Series 1260 Infinity II Binary Pump User Manual 52

3 Using the Pump Solvent Information

Platinum/Iridium

Platinum/Iridium is inert to almost all common acids, bases and solvents. There are no documented incompatibilities for HPLC applications.

Fluorinated polymers (PTFE, PFA, FEP, FFKM, PVDF)

Fluorinated polymers like PTFE (polytetrafluorethylene), PFA (perfluoroalkoxy), and FEP (fluorinated ethylene propylene) are inert to almost all common acids, bases, and solvents. FFKM is perfluorinated rubber, which is also resistant to most chemicals. As an elastomer, it may swell in some organic solvents like halogenated hydrocarbons.

TFE/PDD copolymer tubings, which are used in all Agilent degassers except G1322A/G7122A, are not compatible with fluorinated solvents like Freon, Fluorinert, or Vertrel. They have limited life time in the presence of hexafluoroisopropanol (HFIP). To ensure the longest possible life with HFIP, it is best to dedicate a particular chamber to this solvent, not to switch solvents, and not to let dry out the chamber. For optimizing the life of the pressure sensor, do not leave HFIP in the chamber when the unit is off.

The tubing of the leak sensor is made of PVDF (polyvinylidene fluoride), which is incompatible with the solvent DMF (dimethyl formamide).

Sapphire, Ruby and Al2O3-based ceramics

Sapphire, ruby and ceramics based on aluminum oxide Al2O3 are inert to almost all common acids, bases and solvents. There are no documented incompatibilities for HPLC applications.

InfinityLab LC Series 1260 Infinity II Binary Pump User Manual 53

3 Using the Pump Algae Growth in HPLC Systems

Algae Growth in HPLC Systems

The presence of algae in HPLC systems can cause a variety of problems that may be incorrectly diagnosed as instrument or application problems. Algae grow in aqueous media, preferably in a pH range of 4-8. Their growth is accelerated by buffers, for example phosphate or acetate. Since algae grow through photosynthesis, light will also stimulate their growth. Even in distilled water small-sized algae grow after some time.

Instrumental Problems Associated With Algae

Algae deposit and grow everywhere within the HPLC system, causing the followng problems:

Blocked solvent filters, or deposits on inlet or outlet valves, resulting in unstable flow, composition or gradient problems, or a complete failure of the pump.

Plugging of small-pore, high-pressure solvent filters, usually placed before the injector, resulting in high system pressure.

Blockage of PTFE frits, leading to increased system pressure.

Plugging of column filters, giving high system pressure.

Dirty flow cell windows of detectors, resulting in higher noise levels (since the detector is the last module in the flow path, this problem is less common).

How to Prevent and/or Reduce the Algae Problem Always use freshly prepared solvents, especially use demineralized water

which was filtered through 0.2 m filters.

Never leave mobile phase in the instrument for several days without flow.

Always discard old mobile phase.

Use the amber solvent bottle (Solvent bottle, amber, 1000 mL (9301-6526)) supplied with the instrument for your aqueous mobile phase.

If possible add a few mg/L sodium azide or a few percent organic solvent to the aqueous mobile phase.

InfinityLab LC Series 1260 Infinity II Binary Pump User Manual 54

3 Using the Pump Prevent Blocking of Solvent Filters

Prevent Blocking of Solvent Filters

Contaminated solvents or algae growth in the solvent bottle will reduce the lifetime of the solvent filter and will influence the performance of the module. This is especially true for aqueous solvents or phosphate buffers (pH 4 to 7). The following suggestions will prolong lifetime of the solvent filter and will maintain the performance of the module.

Use a sterile, if possible amber, solvent bottle to slow down algae growth.

Filter solvents through filters or membranes that remove algae.

Exchange solvents every two days or refilter.

If the application permits add 0.0001 0.001 M sodium azide to the solvent.

Place a layer of argon on top of your solvent.

Avoid exposure of the solvent bottle to direct sunlight.

NOTE Never use the system without solvent filter installed.

InfinityLab LC Series 1260 Infinity II Binary Pump User Manual 55

3 Using the Pump Prevent Blocking of Solvent Filters

Checking the Solvent Filters The solvent filters are located on the low-pressure side of the binary pump. A blocked filter therefore does not necessarily affect the high pressure readings of the pump. The pressure readings cannot be used to check whether the filters are blocked or not. If the solvent cabinet is placed on top of the binary pump, the filter condition can be checked in the following way:

Remove the solvent inlet tube from the inlet port of the solvent selection valve or the degasser. If the filter is in good condition, the solvent will freely drip out of the solvent tube (due to hydrostatic pressure). If the solvent filter is partly blocked only very little solvent will drip out of the solvent tube.

Cleaning the Solvent Filters Remove the blocked solvent filter from the bottle-head assembly and place it

in a beaker with concentrated nitric acid (35%) for one hour.

Thoroughly flush the filter with HPLC-grade water (remove all nitric acid, some capillary columns can be damaged by nitric acid).

Replace the filter.

WARNING When opening capillary or tube fittings, solvents may leak out.

The handling of toxic and hazardous solvents and reagents can carry health risks.

Observe appropriate safety procedures (for example, wear goggles, safety gloves and protective clothing) as described in the material handling and safety data sheet supplied by the solvent vendor, especially when toxic or hazardous solvents are used.

NOTE Never use the system without solvent filter installed.

InfinityLab LC Series 1260 Infinity II Binary Pump User Manual 56

3 Using the Pump Normal Phase Applications

Normal Phase Applications

Current passive inlet valves and outlet ball valves used with 1260 and 1290 Infinity pumps do not work well with applications using non-polar solvents as for normal phase applications (e.g. hexane, heptane and CO2). With such applications, pressure drops could be observed. They are a result of particles electrostatically charging up in insulating solvents and sticking to the balls inside the valves, such that the valves do not close properly any more after some time of use (can be hours).

For normal phase applications, a second type of valves is available, which has a design based on the existing one for 1260 and 1290 Infinity valves. These valves use a new material for valve balls, which is a conductive ceramic and replaces non-conductive ruby balls. The balls do not charge up electrostatically and show good performance in normal phase.

The valves are marked with N for non-polar or normal phase.

Agilent recommends using these valves for (and only for) normal phase applications.

No design change has been done for active inlet valves, which have already been used successfully in the past for normal phase applications in 1200 Series and 1260 Infinity binary pumps.

The N-Valves have been tested successfully in using hexane at pressures below 100 bar; heptane can be used as a substitute for neurotoxic hexane.

CAUTION Corrosion of valves

Normal phase balls/valves corrode quickly in aqueous solutions and acids (at or below pH 7).

Do not use normal phase valves in applications running with aqueous solutions.

InfinityLab LC Series 1260 Infinity II Binary Pump User Manual 57

3 Using the Pump Normal Phase Applications

Seals for Normal Phase Applications

For running normal phase applications on 1200 Infinity Series pumps, yellow PE seals are required, which exist as piston seals and wash seals. Seal wash is very uncommon for normal phase applications (no buffers needed), but wash seals are needed for seal wash pump heads.

1290 Infinity pumps use PE seals by default. In combination with ceramic pistons, PE seals are used for both reversed phase (1200 bar) and normal phase applications.

1260 Infinity pumps use sapphire pistons and black PTFE piston and wash seals by default (600 bar). Such PTFE seals create small wear particles in normal phase applications, which can clog valves and other parts in the flow path.

PE seals have a limited life time when used with normal phase solvents and sapphire pistons. Agilent recommends a maximum pressure of 200 bar for this combination, which shall also be applied for pressure tests.

4 Optimizing Performance When to Use a Vacuum Degasser

When to Use a Vacuum Degasser

A degasser removes air, which is dissolved in any solvent. When solvents are heated or mixed with other solvents, air can leave the solvent and form small bubbles. Over time, these bubbles accumulate and can cause pressure fluctuations which may finally result in retention time shifts.

All Agilent 1200 Infinity II Series Pumps have a built-in degasser. While a degasser is needed for low pressure mixing pumps like Agilent quaternary pumps, high pressure mixing pumps like Agilent binary pumps are more robust with respect to bubble formation. However, a degasser is recommended for best performance.

Additionally, a degasser is highly recommended for the following applications:

Your detector is used with maximum sensitivity in the low UV wavelength range.

Your application requires highest injection precision.

Your application requires highest retention-time reproducibility (flow rates below 0.5 mL/min).

The binary pump is used with bypassed damper and mixer.

The external 1260 Infinity II Degasser G7122A is recommended for use with applications using highly volatile solvents like Hexane or DCM, solvents with special characteristics like THF, or applications using refractive index detection.

Operational Hints for the Vacuum Degasser If you are using the vacuum degasser for the first time, if the vacuum degasser was switched off for any length of time (for example, overnight), or if the vacuum degasser chambers are empty, you have to prime the vacuum degasser before running an analysis. Priming is usually done by pumping at a high flow rate (3 5 mL/min). Alternatively, a syringe can be used to draw the solvent through the (empty) degasser if the pump does not aspirate the solvent by itself.

InfinityLab LC Series 1260 Infinity II Binary Pump User Manual 60

4 Optimizing Performance When to Use the Active Seal Wash Option

When to Use the Active Seal Wash Option

Concentrated buffer solutions will reduce the lifetime of the seals and pistons in your binary pump. The active seal wash option allows to maintain the seal lifetime by flushing the low pressure side of the seals with a wash solvent.

The seal wash option is strongly recommended if buffer concentrations of 0.1 M or higher are used regularly with the pump.

The active seal wash option kit can be ordered by quoting Active Seal Wash Upgrade Product including Service (G1399A).

The seal wash option comprises a peristaltic pump, secondary seals, gaskets, seal holders and tubing for both pump heads. A bottle of premixed water/isopropanol (90/10 vol%) is placed in the solvent cabinet and connected to the peristaltic pump.

Always use a mixture of HPLC-grade water (90 %) and isopropanol (10 %) as wash solvent. This mixture prevents bacteria growth in the wash bottle and reduces the surface tension of the water.

The operation of the peristaltic pump can be controlled from the data system or the Instant Pilot.

For adding a seal-wash option, please contact your local Agilent Technologies service representative.

NOTE In order to avoid accumulation of buffer salts or impurities, regularly replace the washing solution using fresh solvents.

4 Optimizing Performance When to Use the Low Volume Mixer

When to Use the Low Volume Mixer

The Low volume mixer ( 200 L) (5067-1565) is designed for use with the Agilent InfinityLab LC Series 1260 Infinity II Binary LC System in low delay volume mode. This configuration is typically used for 2.1 mm i.d., 1.8 m particle size columns, where emphasis is put on S/N ratio. The low volume mixer helps mixing gradients starting with a low concentration of organic solvents, which can cause noise on the baseline.

InfinityLab LC Series 1260 Infinity II Binary Pump User Manual 62

4 Optimizing Performance When to Remove Damper and Mixer

When to Remove Damper and Mixer

The binary pump is equipped with a pressure pulsation damper and a static mixer. The total delay volume of the pump is 600 800 L (depending on system pressure). The mixer has a volume of 400 L.

For applications that require lowest delay volume (for example, fast gradient methods or gradient applications with low flow rates), damper and mixer can be bypassed.

4 Optimizing Performance How to Optimize the Compressibility Compensation Setting

How to Optimize the Compressibility Compensation Setting

When a solvent is metered at ambient pressure and compressed to a higher pressure, the volume decreases depending on its compressibility. Solvent compressibility is a non-linear function of pressure and temperature. It is specific for each solvent.

In order to deliver the desired flow accurately at all pressures, Agilent pumps use a compressibility compensation. For standard LC applications, e.g. using a 400 bar binary pump, an average compressibility value for the solvent is sufficient.

For the 600 bar 1260 Infinity II Binary Pump , the pressure-dependency of a solvent compressibility needs to be considered. It is determined at different pressures between 0 600 bar. The pump uses the obtained non-linear function to select the correct compressibility value for the actual pump pressure. Compressibility data for the most common solvents is readily available in the pump firmware.

The compensation algorithm is so powerful that the damper and mixer can be removed from the pump flow path at low flow rate while the pressure ripple and composition ripple remain at low levels.

For method compatibility reasons, the legacy compressibility compensation is still available.

Solvent Compressibility Calibration Unlisted or premixed solvents can be calibrated with the Solvent Compressibility Calibration function. For a detailed description, see Binary Pump Solvent Compressibility Calibration on page 100.

InfinityLab LC Series 1260 Infinity II Binary Pump User Manual 65

4 Optimizing Performance How to Optimize the Compressibility Compensation Setting

Optimization of Legacy Compressibility Settings

The compressibility compensation default settings are 50 10-6 /bar (best for

most aqueous solutions) for pump head A and 115 10-6 /bar (to suit organic solvents) for pump head B. The settings represent average values for aqueous solvents (A side) and organic solvents (B side). Therefore it is always recommended to use the aqueous solvent on the A side of the pump and the organic solvent on the B side. Under normal conditions, the default settings reduce the pressure pulsation to below 2 % of system pressure, which is sufficient for most applications. If the compressibility values for the solvents used differ from the default settings, it is recommended to change the compressibility values accordingly. Compressibility settings can be optimized by using the values for various solvents described in Table 8 on page 67. If the solvent in use is not listed in the compressibility table, when using premixed solvents and if the default settings are not sufficient for your application, the following procedure can be used to optimize the compressibility settings:

1 Start channel A of the binary pump with the required flow rate.

2 Before starting the optimization procedure, the flow must be stable. Use degassed solvent only. Check the tightness of the system with the pressure test (see (System) Pressure Test on page 93).

3 Your pump must be connected to an Agilent data system or Instant Pilot, the pressure- and %-ripple can be monitored with one of these instruments.

4 Start the recording device in plot mode.

5 Starting with a compressibility setting of 40 10-6 /bar, increase the value in steps of 10. The compressibility compensation setting that generates the smallest pressure ripple is the optimum value for your solvent composition.

6 Repeat step 1 through step 5 for the B channel of your binary pump.

Overview of the Modules Indicators and Test Functions

Status Indicators The module is provided with two status indicators which indicate the operational state of the module. The status indicators provide a quick visual check of the operation of the module.

Error Messages In the event of an electronic, mechanical or hydraulic failure, the module generates an error message in the user interface. For each message, a short description of the failure, a list of probable causes of the problem, and a list of suggested actions to fix the problem are provided (see chapter Error Information).

Test Functions A series of test functions are available for troubleshooting and operational verification after exchanging internal components (see Tests and Calibrations).

Pressure Test The Pressure Test is a quick test designed to determine the pressure tightness of the system (i.e. the high pressure flow path between pump and column). After exchanging flow path components (e.g. pump seals or injection seal), use this test to verify the system is pressure tight, see (System) Pressure Test on page 93.

InfinityLab LC Series 1260 Infinity II Binary Pump User Manual 69

5 Troubleshooting and Diagnostics Overview of the Modules Indicators and Test Functions

Solvent Compressibility Calibration Solvent compressibility is a function of solvent type and pressure. In order to optimize flow accuracy and pressure ripple, the compressibility of the solvent must be considered. The binary pump firmware contains compressibility parameters for most commonly used solvents. A compressibility calibration function is available to generate compressibility data for unlisted solvents (see Binary Pump Solvent Compressibility Calibration on page 100). The compressibility data are stored in an XML file and can be transferred to other InfinityLab LC Series binary pumps.

Pump Elasticity Calibration Various parts in the flow path of the binary pump have a certain elasticity which needs to be compensated to obtain the lowest pressure-, flow- and composition ripple possible. This is done by running an elasticity calibration after maintenance and major repairs. For details see Pump Elasticity Calibration on page 102.

Pump Leak Rate Test The Pump Leak Rate Test is a diagnostic test designed to determine the pressure tightness of the pump components. When a problem with the pump is suspected, use this test to help troubleshoot the pump and its pumping performance, see Pump Leak Rate Test on page 104.

6 Error Information What Are Error Messages

What Are Error Messages

Error messages are displayed in the user interface when an electronic, mechanical, or hydraulic (flow path) failure occurs which requires attention before the analysis can be continued (for example, repair, or exchange of consumables is necessary). In the event of such a failure, the red status indicator at the front of the module is switched on, and an entry is written into the module logbook.

If an error occurs outside a method run, other modules will not be informed about this error. If it occurs within a method run, all connected modules will get a notification, all LEDs get red and the run will be stopped. Depending on the module type, this stop is implemented differently. For example, for a pump the flow will be stopped for safety reasons. For a detector, the lamp will stay on in order to avoid equilibration time. Depending on the error type, the next run can only be started, if the error has been resolved, for example liquid from a leak has been dried. Errors for presumably single time events can be recovered by switching on the system in the user interface.

Special handling is done in case of a leak. As a leak is a potential safety issue and may have occurred at a different module from where it has been observed, a leak always causes a shutdown of all modules, even outside a method run.

In all cases, error propagation is done via the CAN bus or via an APG/ERI remote cable (see documentation for the APG/ERI interface).

The pump motor in the module was unable to move into the correct position for restarting.

When the module is switched on, the first step is to switch on the C phase of the variable reluctance motor. The rotor should move to one of the C positions. The C position is required for the servo to be able to take control of the phase sequencing with the commutator. If the rotor is unable to move, or if the C position cannot be reached, the error message is generated.

7 Test Functions and Calibration (System) Pressure Test

(System) Pressure Test

Description

The system pressure test is a quick built-in test designed to demonstrate the leak tightness of the system. The test involves monitoring the flow profile while the pump delivers against a blank nut. The result is presented as the leak rate of the module and provides information about the leak tightness of the system between the outlet valves of the pump and the blank nut.

Step 1

The test begins with the initialization of both pump heads. After initialization, the pump is starting the compression phase and the required flow rate is constantly monitored and adjusted. The pump continues to pump until a system pressure of around 600 bar is reached.

Step 2

When the system pressure reaches 600 bar, the pump continues to pump at a flow rate that keeps the pressure constant. The flow that is needed to keep the pressure constant is directly translated into a leak rate.

NOTE This Lab Advisor test uses different names depending on the firmware revision used: FW revision > A.06.50: System Pressure Test

NOTE The blank nut can be positioned anywhere between the purge valve of the pump and the detector inlet to pressure test the desired part of the system.

CAUTION Blank nut placed at the outlet of flow cell

The applied pressure may cause permanent leaks or bursting of the flow cell.

Never include the flow cell in the pressure test.

InfinityLab LC Series 1260 Infinity II Binary Pump User Manual 93

7 Test Functions and Calibration (System) Pressure Test

Positioning the Blank Nut To test the complete systems pressure tightness, the blank nut should be positioned at the column compartment outlet (or the outlet of the last module before the detector).

If a specific component is suspected of causing a system leak, place the blank nut immediately before the suspected component, and then run the System Pressure Test again. If the test passes, the defective component is located after the blank nut. Confirm the diagnosis by placing the blank nut immediately after the suspected component. The diagnosis is confirmed if the test fails.

2 Start the test and follow the instructions.

Evaluating the Results The sum of all leaks between the pump and the blank nut will add up to the total leak rate. Note that small leaks may cause the test to fail, but solvent may not be seen leaking from a module.

When The test should be used when problems with small leaks are suspected, or after maintenance of flow path components (e.g., pump seals, injection seal) to prove pressure tightness up to 600 bar

NOTE Make sure to release the pressure by opening the purge valve when the test has completed. Otherwise the pump may generate an overpressure error.

NOTE Please notice the difference between an error in the test and a failure of the test! An error is caused by the abnormal termination during the operation of the test whereas a failure of a test indicates that the test results were not within the specified limits.

InfinityLab LC Series 1260 Infinity II Binary Pump User Manual 95

7 Test Functions and Calibration (System) Pressure Test

If the pressure test fails:

Ensure all fittings between the pump and the blank nut are tight. Repeat the pressure test.

If the test fails again, insert the blank nut at the outlet of the previous module in the stack (e.g. autosampler, port 6 of the injection valve), and repeat the pressure test. Exclude each module one by one to determine which module is leaking.

If the pump is determined to be the source of the leak, run the valve test to identify the defective pump component.

Potential Causes of Pressure Test Failure

After isolating and fixing the cause of the leak, repeat the pressure test to confirm the system is pressure tight.

NOTE Often it is only a damaged blank nut itself (poorly shaped from overtightening) that causes the test to fail. Before investigating on any other possible sources of failure make sure that the blank nut you are using is in good condition and properly tightened!

7 Test Functions and Calibration Valve Test

Valve Test

Description

The Valve Test provides a fast and accurate way to verify proper hydraulic operation of the binary pump. Problems that are related to defective valves, seals or pistons can be diagnosed and usually the defective part is identified.

Step 1

The system is setup with water on both channels and a restriction capillary is attached to the outlet of the pump. Pump head A is delivering at 1 mL/min. The pressure signal is monitored and overlaid with the piston movement plot. The pressure pattern and the slope of the pressure signal are evaluated for the delivery strokes of both pistons.

Step 2

The procedure from step 1 is repeated on pump head B.

Step 3

The data from step 1 and 2 are evaluated. In case test failed, a conclusion about the defective part is made.

7 Test Functions and Calibration Binary Pump Solvent Compressibility Calibration

Binary Pump Solvent Compressibility Calibration

Description

Each solvent or solvent mixture has unique compressibility at different pressures. In order to deliver accurate flow with minimal pressure- and composition ripple over the full operational pressure range, it is necessary that the pump compensates precisely for the compressibility of the solvents in use.

The binary pump comes with compressibility parameters for the most common HPLC solvents and solvent mixtures. If a solvent is not available in the list of pre-calibrated solvents, the solvent compressibility calibration allows the appropriate compressibility data to be generated.

Technical background

The solvent compressibility calibration relies on an accurate elasticity calibration of the pump. With a proper elasticity calibration in place, the pump is switched into pressure control mode. A restriction capillary is connected to the purge valve outlet. By varying the flow rate, the pump maintains a certain pressure. The pump optimizes the compressibility value of the solvent until the lowest possible pump ripple is reached. The pump increases the flow rate and adjusts the pressure to the next calibration step where the pump ripple is minimized again. This process is repeated until solvent compressibility data for the whole operating pressure range of the pump are available.

The compressibility data set for this solvent is stored in an XML-file on the desktop. It can be shared with other InfinityLab LC Series binary pumps via the controlling data system.

InfinityLab LC Series 1260 Infinity II Binary Pump User Manual 101

7 Test Functions and Calibration Pump Elasticity Calibration

Pump Elasticity Calibration

Description

The flow path components of the binary pump have an inherent and pressure dependent elasticity which differs from pump to pump. When this elasticity/pressure function is known, a correction algorithm can be applied. This results in significantly improved pump performance in low delay volume mode (damper and mixer bypassed).

The pump elasticity calibration uses a solvent with well known properties (HPLC-grade water) to determine the pump elasticity over the entire operating pressure range and stores the calibration values in the non-volatile RAM of the pump mainboard.

The initial calibration is done at the factory. It only needs to be repeated after replacement of major pump parts (mainboard, pump drive). The test allows to define which pump head will be calibrated.

NOTE Results of the pump elasticity calibration rely on known compressibility parameters for pure water. If the water is not HPLC-grade, not well degassed or degasser and pump are not flushed properly, the pump elasticity calibration will fail. The pump elasticity calibration has to be performed for each pump head individually.

CAUTION Incorrect pump elasticity calibration.

Solvent compressibility calibrations acquired with a miscalibrated pump will work, but they are not transferable to other pumps. A correct pump elasticity calibration is an essential prerequisite for successful solvent compressibility calibrations.

Calibrate the pump elasticity correctly.

Primary Leak

If a leak is found for movement of piston 1 (primary leak), any leak described for piston movement 2 will cause a failure for piston 1 as well, as the liquid can move through the outlet valve to chamber 2. Such cases need to be identified as described before. Additionally, following causes are possible:

Internal Outlet Valve Leak

A leak of the outlet valve will be identified separately (internal outlet valve leak) by calculating the difference between leak rate 1 and leak rate 2. If the second leak rate is higher than the first one, this is due to a flow back through the outlet valve.

Probable cause Suggested actions

1 Leak at piston 1 or seal in chamber 1 Inspect piston, replace piston and/or seal

2 Leak at inlet valve Replace inlet valve or inlet valve cartridge (AIV only)

Probable cause Suggested actions

1 Put a bottle with 100 ml of isopropanol in the solvent cabinet and place the solvent intake filter of the pump head you want to wear in into this bottle.

2 Screw the PEEK adapter 1/4-28 to 10-32 (0100-1847) onto the active inlet valve and connect the inlet tube from the bottle head directly to it.

3 Connect the Restriction capillary (5022-2159) to the purge valve. Connect its other end to a waste container.

4 Open the purge valve and purge the system for 5 min with isopropanol at a flow rate of 2 mL/min.

5 Close the purge valve, set the flow to a value that gives a pressure of 580 bar. Pump 15 min at this pressure to wear the seals in. The pressure can be monitored with the Instant Pilot, chromatographic data system or any other controlling device connected to your pump.

6 Turn OFF the pump, slowly open the purge valve to release the pressure from the system, disconnect the restriction capillary and reconnect the outlet capillary to the purge valve. Reconnect the intake tubing to the solvent selection valve and the connecting tube from the solvent selection valve (if installed) to the AIV.

7 Purge your system with the solvent used for your next application.

a non-instrument specific section, called resident system

an instrument specific section, called main system

Resident System

This resident section of the firmware is identical for all Agilent 1100/1200/1220/1260/1290 series modules. Its properties are:

the complete communication capabilities (CAN, LAN, USB and RS- 232)

memory management

ability to update the firmware of the 'main system'

Main System

Its properties are:

the complete communication capabilities (CAN, LAN, USB and RS- 232)

memory management

ability to update the firmware of the 'resident system'

In addition the main system comprises the instrument functions that are divided into common functions like

run synchronization through APG/ERI remote,

error handling,

diagnostic functions,

or module specific functions like

internal events such as lamp control, filter movements,

raw data collection and conversion to absorbance.

11 Hardware Information Firmware Description

The firmware update tools, firmware and documentation are available from the Agilent web.

http://www.agilent.com/en-us/firmwareDownload?whid=69761

NOTE Some modules are limited in downgrading due to their mainboard version or their initial firmware revision. For example, a G1315C DAD SL cannot be downgraded below firmware revision B.01.02 or to a A.xx.xx.

Some modules can be re-branded (e.g. G1314C to G1314B) to allow operation in specific control software environments. In this case, the feature set of the target type is used and the feature set of the original one is lost. After re-branding (e.g. from G1314B to G1314C), the original feature set is available again.

All this specific information is described in the documentation provided with the firmware update tools.

InfinityLab LC Series 1260 Infinity II Binary Pump User Manual 182

11 Hardware Information Electrical Connections

Electrical Connections

The CAN bus is a serial bus with high-speed data transfer. The two connectors for the CAN bus are used for internal module data transfer and synchronization.

The ERI/REMOTE connector may be used in combination with other analytical instruments from Agilent Technologies if you want to use features such as start, stop, common shutdown, prepare, and so on.

With the appropriate software, the LAN connector may be used to control the module from a computer through a LAN connection. This connector is activated and can be configured with the configuration switch.

With the appropriate software, the USB connector may be used to control the module from a computer through a USB connection.

The power input socket accepts a line voltage of 100 240 VAC 10 % with a line frequency of 50 or 60 Hz. Maximum power consumption varies by module. There is no voltage selector on your module because the power supply has wide-ranging capability. There are no externally accessible fuses because automatic electronic fuses are implemented in the power supply.

NOTE Never use cables other than the ones supplied by Agilent Technologies to ensure proper functionality and compliance with safety or EMC regulations.

InfinityLab LC Series 1260 Infinity II Binary Pump User Manual 186

11 Hardware Information Interfaces

Overview Interfaces

CAN

The CAN is inter-module communication interface. It is a 2-wire serial bus system supporting high speed data communication and real-time requirement.

LAN

The modules have either an interface slot for a LAN card (e.g. Agilent G1369B/C LAN Interface) or they have an on-board LAN interface (e.g. detectors G1315C/D DAD and G1365C/D MWD). This interface allows the control of the module/system via a PC with the appropriate control software. Some modules have neither on-board LAN nor an interface slot for a LAN card (e.g. G1170A Valve Drive or G4227A Flexible Cube). These are hosted modules and require a Host module with firmware B.06.40 or later or with additional G1369C LAN Card.

USB

The USB interface replaces the RS-232 Serial interface in new FUSION generation modules. For details on USB refer to USB (Universal Serial Bus) on page 192.

Analog Signal Output

The analog signal output can be distributed to a recording device. For details refer to the description of the modules mainboard.

NOTE If an Agilent detector (DAD/MWD/FLD/VWD/RID) is in the system, the LAN should be connected to the DAD/MWD/FLD/VWD/RID (due to higher data load). If no Agilent detector is part of the system, the LAN interface should be installed in the pump or autosampler.

InfinityLab LC Series 1260 Infinity II Binary Pump User Manual 187

11 Hardware Information Interfaces

Remote (ERI)

The ERI (Enhanced Remote Interface) connector may be used in combination with other analytical instruments from Agilent Technologies if you want to use features as common shut down, prepare, and so on.

It allows easy connection between single instruments or systems to ensure coordinated analysis with simple coupling requirements.

The subminiature D connector is used. The module provides one remote connector which is inputs/outputs (wired- or technique).

To provide maximum safety within a distributed analysis system, one line is dedicated to SHUT DOWN the systems critical parts in case any module detects a serious problem. To detect whether all participating modules are switched on or properly powered, one line is defined to summarize the POWER ON state of all connected modules. Control of analysis is maintained by signal readiness READY for next analysis, followed by START of run and optional STOP of run triggered on the respective lines. In addition PREPARE and START REQUEST may be issued. The signal levels are defined as:

standard TTL levels (0 V is logic true, + 5.0 V is false),

fan-out is 10,

input load is 2.2 kOhm against + 5.0 V, and

output are open collector type, inputs/outputs (wired- or technique).

NOTE All common TTL circuits operate with a 5 V power supply. A TTL signal is defined as "low" or L when between 0 V and 0.8 V and "high" or H when between 2.0 V and 5.0 V (with respect to the ground terminal).

11 Hardware Information Interfaces

ERI (Enhanced Remote Interface) ERI replaces the AGP Remote Interface that is used in the HP 1090/1040/1050/1100 HPLC systems and Agilent 1100/1200/1200 Infinity HPLC modules. All new InfinityLab LC Series products using the FUSION core electronics use ERI. This interface is already used in the Agilent Universal Interface Box 2 (UIB2)

ERI Description

The ERI interface contains eight individual programmable input/output pins. In addition, it provides 24 V power and 5 V power and a serial data line to detect and recognize further add-ons that could be connected to this interface.

Special Settings

Boot-Resident/Main

Firmware update procedures may require this mode in case of firmware loading errors (main/resident firmware part).

If you use the following switch settings and power the instrument up again, the instrument firmware stays in the resident/main mode. In resident mode, it is not operable as a module. It only uses basic functions of the operating system for example, for communication. In this mode the main firmware can be loaded (using update utilities).

Forced Cold Start

A forced cold start can be used to bring the module into a defined mode with default parameter settings.

Boot Main System / Revert to Default Data

The instrument will boot to main mode and changes to the modules default parameter. May be also required to load resident firmware into the module.

Boot Resident System / Revert to Default Data

The instrument will boot to resident mode and changes to the modules default parameter. May be also required to load main firmware into the module.

If you use the following switch settings and power the instrument up again, it will start as described above.

CAUTION Loss of data

Forced cold start erases all methods and data stored in the non-volatile memory. Exceptions are calibration settings, diagnosis and repair log books which will not be erased.

Save your methods and data before executing a forced cold start.

11 Hardware Information Early Maintenance Feedback

Early Maintenance Feedback

Maintenance requires the exchange of components that are subject to wear or stress. Ideally, the frequency at which components are exchanged should be based on the intensity of use of the module and the analytical conditions, and not on a predefined time interval. The early maintenance feedback (EMF) feature monitors the use of specific components in the instrument, and provides feedback when the user-selectable limits have been exceeded. The visual feedback in the user interface provides an indication that maintenance procedures should be scheduled.

EMF Counters

EMF counters increment with use and can be assigned a maximum limit which provides visual feedback in the user interface when the limit is exceeded. Some counters can be reset to zero after the required maintenance procedure.

Using the EMF Counters

The user-settable EMF limits for the EMF Counters enable the early maintenance feedback to be adapted to specific user requirements. The useful maintenance cycle is dependent on the requirements for use. Therefore, the definition of the maximum limits need to be determined based on the specific operating conditions of the instrument.

Setting the EMF Limits

The setting of the EMF limits must be optimized over one or two maintenance cycles. Initially the default EMF limits should be set. When instrument performance indicates maintenance is necessary, take note of the values displayed by the EMF counters. Enter these values (or values slightly less than the displayed values) as EMF limits, and then reset the EMF counters to zero. The next time the EMF counters exceed the new EMF limits, the EMF flag will be displayed, providing a reminder that maintenance needs to be scheduled.

11 Hardware Information Instrument Layout

Instrument Layout

The industrial design of the module incorporates several innovative features. It uses Agilents E-PAC concept for the packaging of electronics and mechanical assemblies. This concept is based upon the use of expanded polypropylene (EPP) layers of foam plastic spacers in which the mechanical and electronic boards components of the module are placed. This pack is then housed in a metal inner cabinet which is enclosed by a plastic external cabinet. The advantages of this packaging technology are:

virtual elimination of fixing screws, bolts or ties, reducing the number of components and increasing the speed of assembly/disassembly,

the plastic layers have air channels molded into them so that cooling air can be guided exactly to the required locations,

the plastic layers help cushion the electronic and mechanical parts from physical shock, and

the metal inner cabinet shields the internal electronics from electromagnetic interference and also helps to reduce or eliminate radio frequency emissions from the instrument itself.

What You Have to Do First

The module has an on- board LAN communication interface.

1 Note the MAC (Media Access Control) address for further reference. The MAC or hardware address of the LAN interfaces is a world wide unique identifier. No other network device will have the same hardware address. The MAC address can be found on a label at the rear of the module underneath the configuration switch (see Figure 24 on page 200).

Figure 23 MAC-Label

2 Connect the instrument's LAN interface (see Figure 24 on page 200) to

the PC network card using a crossover network cable (point-to-point) or

a hub or switch using a standard LAN cable.

12 LAN Configuration TCP/IP parameter configuration

TCP/IP parameter configuration

To operate properly in a network environment, the LAN interface must be configured with valid TCP/IP network parameters. These parameters are:

IP address

Subnet Mask

Default Gateway

The TCP/IP parameters can be configured by the following methods:

by automatically requesting the parameters from a network-based DHCP Server (using the so-called Dynamic Host Configuration Protocol). This mode requires a LAN-onboard Module or a G1369C LAN Interface card, see Setup (DHCP) on page 206

by manually setting the parameters using Telnet

by manually setting the parameters using the Local Controller

The LAN interface differentiates between several initialization modes. The initialization mode (short form init mode) defines how to determine the active TCP/IP parameters after power-on. The parameters may be derived non-volatile memory or initialized with known default values. The initialization mode is selected by the configuration switch, see Table 18 on page 203.

InfinityLab LC Series 1260 Infinity II Binary Pump User Manual 201

12 LAN Configuration Configuration Switches

12 LAN Configuration Initialization Mode Selection

Initialization Mode Selection

The following initialization (init) modes are selectable:

Default IP address for LAN is 192.168.254.11.

DHCP address is the modules LAN MAC address.

Using Stored

When initialization mode Using Stored is selected, the parameters are taken from the non-volatile memory of the module. The TCP/IP connection will be established using these parameters. The parameters were configured previously by one of the described methods.

Figure 26 Using Stored (Principle)

Table 18 Initialization Mode Switches

InfinityLab LC Series 1260 Infinity II Binary Pump User Manual 203

12 LAN Configuration Initialization Mode Selection

Using Default

When Using Default is selected, the factory default parameters are taken instead. These parameters enable a TCP/IP connection to the LAN interface without further configuration, see Table 19 on page 204.

Figure 27 Using Default (Principle)

Since the default IP address is a so-called local address, it will not be routed by any network device. Thus, the PC and the module must reside in the same subnet.

The user may open a Telnet session using the default IP address and change the parameters stored in the non-volatile memory of the module. He may then close the session, select the initialization mode Using Stored, power-on again and establish the TCP/IP connection using the new parameters.

When the module is wired to the PC directly (e.g. using a cross-over cable or a local hub), separated from the local area network, the user may simply keep the default parameters to establish the TCP/IP connection.

Active Parameter

Default Parameter

NOTE Using the default address in your local area network may result in network problems. Take care and change it to a valid address immediately.

Table 19 Using Default Parameters

IP address: 192.168.254.11

Subnet Mask: 255.255.255.0

Default Gateway not specified

NOTE In the Using Default mode, the parameters stored in the memory of the module are not cleared automatically. If not changed by the user, they are still available, when switching back to the mode Using Stored.

12 LAN Configuration Dynamic Host Configuration Protocol (DHCP)

Dynamic Host Configuration Protocol (DHCP)

General Information (DHCP) The Dynamic Host Configuration Protocol (DHCP) is an auto configuration protocol used on IP networks. The DHCP functionality is available on all Agilent HPLC modules with on-board LAN Interface or LAN Interface Card G1369C, and B-firmware (B.06.40 or above) or modules with "D"-firmware. All modules should use latest firmware from the same set.

When the initialization mode DHCP is selected, the card tries to download the parameters from a DHCP Server. The parameters obtained become the active parameters immediately. They are not stored to the non-volatile memory of the card.

Besides requesting the network parameters, the card also submits its hostname to the DHCP Server. The hostname equals the MAC address of the card, e.g. 0030d3177321. It is the DHCP server's responsibility to forward the hostname/address information to the Domain Name Server. The card does not offer any services for hostname resolution (e.g. NetBIOS).

Figure 28 DHCP (Principle)

DHCP Server

Active Parameter

NOTE 1 It may take some time until the DHCP server has updated the DNS server with the hostname information.

2 It may be necessary to fully qualify the hostname with the DNS suffix, e.g. 0030d3177321.country.company.com.

3 The DHCP server may reject the hostname proposed by the card and assign a name following local naming conventions.

Manual Configuration

Manual configuration only alters the set of parameters stored in the non-volatile memory of the module. It never affects the currently active parameters. Therefore, manual configuration can be done at any time. A power cycle is mandatory to make the stored parameters become the active parameters, given that the initialization mode selection switches are allowing it.
