3000 Micro GC Operating Manual
4.2.4.3 Setting the Gas Pressure
Set the carrier gas regulator as shown in Table 4-1 .
WARNING
Never fill the Portable 3000 Micro GC internal gas
cylinder with hydrogen. A hydrogen leak inside the
instrument can present an explosion hazard.
CAUTION
Exceeding 82 PSI for the carrier gas pressure may result
in damage to 3000 Micro GC.
CAUTION
Carrier gas pressure below 78 PSI will negatively affect
3000 Micro GC operation.
4.2.4.4 Purge the Carrier Gas Line
Ensure the gas line is not connected to the instrument. Purge carrier gas supply
lines to remove air by opening the tank and letting the carrier gas flow for
five to ten seconds.
