3000 Micro GC Operating Manual
4.1.5 Gas and Regulator Requirements
4.1.5.1 Carrier Gas and Regulator Requirements
A continuous, controlled flow of carrier gas is required.
Use high purity grade gas specifically intended for chromatographic use. All carrier
gas types should be 99.995% to 99.9995% pure.
The carrier gas tank requires a dual stage regulator capable of delivering
80 to 82 PSI of gas pressure. The regulator outlet fitting must be adapted to
Swagelok in order to connect the tubing. Use 1/8 in. fittings or 1/8 in. adapters.
CAUTION
Exceeding 82 PSI for the carrier gas pressure may result
in instrument damage.
CAUTION
To protect 3000 Micro GC and to enhance performance,
carrier gas traps must be used to purify the carrier gas
before the carrier gas is introduced into 3000 Micro GC.
A hydrocarbon/moisture trap (PN G2870A-01) is usually
sufficient.
4.1.5.2 Calibration Gas and Regulator Requirements
Obtain an ample supply of a calibration gas, specific to the analysis needs, from a
commercial vendor.
For the most accurate measurements, use a calibration gas that closely resembles
the actual sample gas composition.
A regulator specific to the calibration gas cylinder should be used. The regulator
should be capable of supplying output pressure from ambient to 25 PSI. The
regulator must be clean, grease free and non-venting.
CAUTION
Checkout gas mixtures supplied by INFICON are not
calibration gases. Checkout gas mixtures are only used
for instrument installation and start up.
