1 Introduction to the High Temperature Viscometer Introduction to the High Temperature Viscometer

Introduction to the High Temperature Viscometer

The Agilent High Temperature viscometer is based on the proven four-capillary design and is intended for online measurement of viscosity when integrated into the 1260 Infinity II High Temperature GPC system. The combination of refractive index (RI) and viscosity detection provides accurate molecular weight determination for all polymer types based on the universal principle, as well as valuable branching information not otherwise obtainable from a concentration detector alone.

Due to the four-capillary technology, the differential pressure (DP) signal is very stable against flow rate fluctuations. A continuous monitor of the pressure through the bridge network also provides a consistent reference of the flow system, the inlet pressure (IP). The instrument can be used in both a batch mode, which yields an average intrinsic viscosity, and a true gel permeation chromatography (GPC) mode, which yields a slice-by-slice intrinsic viscosity distribution. From the intrinsic viscosity and known retention volumes or known Mark-Houwink-Sakurada coefficients, the molecular weight as well as distribution of a polymer may be determined.

The Agilent high temperature viscometer consists of four components:

1 Precision-engineered 4-capillary bridge

2 High sensitivity pressure transducers

3 Electronic control module

4 Discrete 5 V power supply module (PSU)

The viscometer bridge is located in the Agilent column oven. The pressure transducer assembly is housed in the side panel of the Agilent High Temperature GPC system. The electronic control module, where the differential pressure (DP) and inlet pressure (IP) signals are obtained, is stand-alone and located alongside the GPC system.

Introduction to the High Temperature Viscometer 1 How the Detector Operates

How the Detector Operates

When a polymer dissolves in a liquid, the interaction of the two components stimulates an increase in polymer dimensions over that of the unsolvated state. Due to the vast difference in size between solvent and solute, the frictional properties of the solvent in the mixture are drastically altered, and an increase in viscosity occurs which should reflect the size and shape of the dissolved solute, even in dilute solutions.

The dissolved polymer coil disturbs the linear flow of solvent, resulting in a resistance to flow, which is observed as an increase in viscosity.

This was first recognized in 1930 by Staudinger, who found an empirical relation between relative magnitude of increase in viscosity and the molar mass of the polymer.

The intrinsic viscosity [] is a measure of the viscosity of a polymer solution, as the concentration tends to zero, that is at very low concentrations. It is this parameter, therefore that is a characteristic of isolated polymer chains in solution and can be considered to be proportional to the density of the polymer coil. For a given polymer and solvent system at a specified temperature, [] can be related to molecular weight, M, through the Mark-Houwink-Sakurada equation:

where K and are coefficients specific to the polymer, solvent system and temperature. These can be determined by calibrating with polymer standards of known molecular weights. A plot of Log() versus Log(M), a Mark-Houwink-Sakurada plot, will be a straight line as long as the universal calibration is obeyed.

Values of reflect the size of the molecule in solution and for a random coil polymer, range between 0.5 for a polymer dissolved in a theta solvent to about 0.8 in a very good solvent.

Introduction to the High Temperature Viscometer 1 Universal Calibration

Universal Calibration

Benoit (1967) showed that polymers of different structure fall on the same calibration curve if the intrinsic viscosity is included as a calibration parameter. A calibration plot of the product of intrinsic viscosity and molecular weight ([]*M) versus elution volume is a "universal calibration" as shown in Figure 2 on page 12. This allows the system to be calibrated with polymer standards of one type and then analyze polymers of another type and still obtain accurate molecular weight distributions.

Agilent 1260 Infinity II High Temperature Viscometer User Manual 11

1 Introduction to the High Temperature Viscometer Universal Calibration

Figure 2 A universal calibration plot

Therefore for an unknown polymer sample the universal calibration is used to convert the intrinsic viscosity, determined for each slice across the distribution from the viscometer, to molecular weight.

Introduction to the High Temperature Viscometer 1 Polymer Branching

Polymer Branching

The determination of the degree of long chain branching has long occupied polymer chemists. In polymer solutions, the branching factor, g, is the starting point for many branching calculations:

1 Introduction to the High Temperature Viscometer Detection Principle

Detection Principle

The Agilent 1260 High Temperature Viscometer employs the fluid flow equivalent of the analogous wheatstone bridge electrical circuit. Solvent travels down a bridge of four capillaries of equal resistance arranged as shown in Figure 3 on page 14.

Figure 3 Plumbing Diagram of Agilent 1260 High Temperature Viscometer

The differential pressure transducer monitors the pressure drop across the bridge, P, and the inlet pressure transducer measures the pressure drop through the bridge, Pi. When the sample is introduced across capillary (C4) of the bridge, an imbalance is caused due to the hold-up columns. This change in pressure, P, is proportional to the specific viscosity, sp, according to the following equation:

where

P differential pressure across the bridge

Pi pressure of the flow through the capillary bridge

SP = Pi 2P 4P

14 Agilent 1260 Infinity II High Temperature Viscometer User Manual

Introduction to the High Temperature Viscometer 1 Detection Principle

The instrument makes a true differential measurement directly, making it very sensitive to dilute solution viscosity measurements. The intrinsic viscosity, [] is ideally obtained by measuring the specific viscosity values at several finite concentrations and extrapolate to zero concentration.

However, the concentrations used in GPC are low enough for the equation to be valid over a typical chromatogram, and thus an extrapolation to the true intrinsic viscosity is not required, since the concentration is close enough to the limiting concentration.

All of the data acquisition and data processing are accomplished using the Agilent GPC-SEC software, which enables calculation of molecular weight and intrinsic viscosity distributions using algorithms for Universal Calibration.

Branching information can also be obtained.

2 Site Requirements and Specifications Site Requirements

Site Requirements

A suitable environment is important to ensure optimal performance of the instrument.

Power Considerations The module power supply has wide ranging capability. It accepts any line voltage in the range described in Table 1 on page 21. Consequently there is no voltage selector in the rear of the module. There are also no externally accessible fuses, because automatic electronic fuses are implemented in the power supply.

WARNING Hazard of electrical shock or damage of your instrumentation can result, if the devices are connected to a line voltage higher than specified.

Connect your instrument to the specified line voltage only.

WARNING The module is partially energized when switched off, as long as the power cord is plugged in. Repair work at the module can lead to personal injuries, e.g. electrical shock, when the cover is opened and the module is connected to power.

Always unplug the power cable before opening the cover.

Do not connect the power cable to the instrument while the covers are removed.

WARNING Inaccessible power plug. In case of emergency it must be possible to disconnect the instrument from the power line at any time.

Make sure the power connector of the instrument can be easily reached and unplugged.

Provide sufficient space behind the power socket of the instrument to unplug the cable.

2 Site Requirements and Specifications Site Requirements

Bench Space The module dimensions and weight (see Table 1 on page 21) allow you to place the module on a bench next to the 1260 Infinity II HT GPC System. It needs an additional 2.5 cm (1.0 inches) of space on either side and approximately 8 cm (3.1 inches) in the rear for air circulation and electric connections.

If the bench shall carry a complete GPC system, make sure that the bench is designed to bear the weight of all modules.

The module should be operated in a horizontal position.

Environment Your module will work within the specifications at ambient temperatures and relative humidity described in Table 1 on page 21.

ASTM drift tests require a temperature less than 2 C/h (3.6 F/h) over one hour period. Our published drift specification (refer also to Table 2 on page 22) is based on these conditions. Larger ambient temperature changes will result in larger drift.

Drift performance depends on control of the temperature environment fluctuations. To realize the highest performance, minimize the frequency and the amplitude of the temperature changes to below 1 C/h (1.8 F/h).

CAUTION Condensation within the module Condensation can damage the system electronics.

Do not store, ship or use your module under conditions where temperature fluctuations could cause condensation within the module.

If your module was shipped in cold weather, leave it in its box and allow it to warm slowly to room temperature to avoid condensation.

NOTE This module is designed to operate in a typical electromagnetic environment, that is where RF transmitters such as mobile telephones may not be used in close proximity.

NOTE The Agilent Viscometer also has a specific viscosity output that is obtained from the VISC outport. The specific viscosity output cannot be used with Cirrus Multi.

NOTE Powering the control module off and on will reset the output offsets.

NOTE The lengths of the inlet tubes are such as to obtain a flow split between the viscometer NOTE and RI of between 50 and 70 %. For flow split ratio calculations, see Flow Split Ratio Calculations on page 26.

Agilent 1260 Infinity II High Temperature Viscometer User Manual 25

3 Installing the High Temperature Viscometer Flow Split Ratio Calculations

Flow Split Ratio Calculations

The flow split ratio is the ratio between the recorded inlet pressures (IP) from the viscometer with and without the RI detector connected in the system.

Therefore, if the flow split ratio is 60 %, then 60 % of the flow are going through the viscometer, that is, if running the system at 1 mL/min then the flow through the viscometer is 0.6 mL/min.

FlowSplitRatio = IP(Visc Only)

IP(RI+Visc) * 100

Appendix 7 Solvent Information

Solvent Information

Observe the following recommendations on the use of solvents.

Brown glass ware can avoid growth of algae.

Avoid the use of the following steel-corrosive solvents:

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

high concentrations of inorganic acids like sulfuric acid and nitric acid, especially at higher temperatures (if your chromatography method allows, replace 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:

2CHCl3 + O2 2COCl2 + 2HCl

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, di-isopropyl ether) should be filtered through dry aluminium oxide which adsorbs the peroxides,

solvents containing strong complexing agents (e.g. EDTA),

mixtures of carbon tetrachloride with 2-propanol or THF.

Avoid the use of dimethyl formamide (DMF). Polyvinylidene fluoride (PVDF), which is used in leak sensors, is not resistant to DMF.
