Carrier Gas Refill Instructions

490 Micro GC Field Case User Manual

Your Micro GC field case is equipped with refillable, high pressure carrier supply cylinders which have been approved to 12,400 kPa. The 2-channel field case is equipped with two 75mL gas cylinders. The 4-channel field case is quipped with either one or two 300mL gas cylinders.

When the instrument is in use, the Micro GC needs at least 550 10 kPa (80 2 psi) to work properly.

Refilling is done by means of a carrier gas refill assembly.

This special tool is connected directly to the valve on the gas supply cylinder. Because this connection differs from country to country, Agilent Technologies, Inc. offers a range of Refill Assemblys to meet all major standards. If the connector of this device, despite a careful choice, does not match your supply unit, ask your local gas supplier for the right part. It should have 1/4 inch NPT male thread at one end. Exchanging is easy.

Battery handling

Never disassemble the battery as the electrolyte inside is strong alkaline and can damage skin and clothes.

Never attempt to short-circuit the battery. Doing so can damage the product and generated heat can cause burns.

Do not dispose of the battery in a fire. Disposing of the battery in fire can cause the battery to rupture. Also avoid placing batteries in water as this causes batteries to cease to function.

Never solder anything directly to the battery. This can destroy the safety features of the battery by damaging the safety vent inside the cap.

Do not use the battery in an appliance or for purposes for which it was not intended.

Do not place containers with flammable liquids near the battery. Spilling liquid over hot parts may cause fire.

Never use alcohol or thinners to clean the Battery Pack. These chemicals can damage the case.

Charging

490 Micro GC Field Case User Manual

In order to take full advantage of the properties of the Ni-MH Battery Pack and to prevent problems due to improper use, note the following points when charging.

WARNING Charge the battery within an ambient temperature range of 0 C to 45 C.

WARNING Never attempt reverse charging. Charging with polarity reversed can cause a gas pressure inside the batter to rise, which can activate the safety vent, lead to alkaline electrolyte leakage, rapid deterioration ini battery performance, battery swelling, or battery rupture.

Batteries should always be charged prior to use. Be sure to charge correctly, and use only the battery charger that has been supplied by Agilent Technologies, Inc.

The batteries can be charged with the external charger or from in the field case. It is recommended that the batteries be charged in the field case.

Ambient temperature affects charging efficiency. As charging efficiency is best within a temperature range of 10 C to 45 C, when charging, be sure the Battery Pack and charger are within this temperature range.

At temperatures below 0 C the gas absorption reaction is not adequate, causing gas pressure inside the battery to rise, which can activate the safety vent and lead to leakage of alkaline gas and deterioration in performance and battery leakage.

Do not parallel charge batteries.

Avoid overcharging when using the external charger. Repeated overcharging can lead to deterioration in performance. Overcharging means charging a battery when it is already fully charged.

To avoid overcharging, use a timer to measure the total charge time.

3 Battery Pack and Charger

When charging for the first time after long-term storage, deactivation of reactants may lead to increased battery voltage and decreased battery capacity. Restore such batteries to original performance by using the external charger and repeating several cycles of charging and discharging.

When recharging, place the battery in a suitable location with sufficient ventilation. Space around the battery must be sufficient to enable cooling.

Never reverse charge or overcharge with high currents. Doing so causes rapid gas generation and increased gas pressure, thus causing batteries to swell or rupture.

Never insert the battery with the positive and negative poles reversed as this can cause the battery to swell or rupture.

Do not charge the battery if there is a possibility of any kind of electrical damage. Instead, disconnect the battery power cords and contact your Agilent Technologies office.

Discharging

Since over-discharging (deep discharge) damages the battery characteris-

Storage

CAUTION tics do not leave the battery connected to the instrument for long periods of time.

When storing batteries for more than 1 year, disconnect batteries from the

CAUTION field case. Charge at least once per year to prevent leakage and deteriora- tion in performance due to self-discharging.

Store the battery in a dry location with low humidity, no corrosive gases, and at a temperature range of -20 C to +50 C.

Storing the battery in a location where humidity is extremely high or where temperatures fall below -20 C or above +50 C can lead to rusting of metallic parts and battery leakage due to expansion or contraction of parts composed of organic materials.

Long-term storage can accelerate battery self-discharging and lead to the deactivation of reactants; locations where the temperature ranges between +10 C and +30 C are suitable for long-term storage.

490 Micro GC Field Case User Manual

When charging for the first time after long-term storage, deactivation of reactants may lead to increased battery voltage and decreased battery capacity. Restore such batteries to their original performance by using the external charger and repeating several cycles of charging and discharging.

Battery service life

Batteries used under proper conditions of charging and discharging can be used 500 cycles or more.

Batteries are chemical products involving internal chemical reactions. Performance deteriorates not only with use but also during prolonged storage.

Normally, a battery will last two years (or 500 cycles) if used under proper conditions and not overcharged or overdischarged.

However, failure to satisfy conditions concerning charging, temperature, and other factors during actual use can lead to shortened life (or cycle life), damage to products, and deterioration in performance due to leakage and shortened service life.

Significantly reduced service time in spite of proper charging means that the life of the battery has been exceeded. At the end of service life, an increase in internal resistance or an internal short-circuit failure may occur.

Cleaning

To keep the Battery Pack surface clean:

Clean only when the Battery Pack is disconnected from the charger.

Use a soft (not hard or abrasive) brush to carefully brush away all dust and dirt.

If the outer case is dirty (never clean the inside!), clean it with a soft, clean cloth dampened with mild detergent.

Never use alcohol or thinners to clean the Battery Pack, these chemicals can damage the case.

Be careful not to get water on the electronics components.

Do not use compressed air to clean the battery pack.
