Applying carrier and actuation gas
WARNING
Do not use hydrogen as actuation gas. Only helium can be used as an actuation gas.
NOTICE
Applying carrier gas without actuation gas can result in a direct path of the carrier gas to
the vent that rapidly uses up the carrier gas supply.
Apply carrier and actuation gas from the same line
Procedure
1. Back off the bottle regulator so that when you open the bottle valve, there will be no
2. Open the bottle valve.
3. Slowly increase the regulated pressure to 90 psig (6.2 barg).
4. Leak check the lines from the bottle to the gas chromatograph (GC).
Apply carrier gas and actuation gas separately
Prerequisites
If using a separate actuation gas supply, apply pressure and leak check the actuation gas
first and then repeat for the carrier gas.
Procedure
1. Back off the bottle regulator for the actuation gas, so that when you open the bottle
2. Open the actuation gas bottle valve.
3. Slowly increase the regulated pressure of the actuation gas to 90 psig (6.2 barg).
4. Leak check the lines from the actuation gas bottle to the gas chromatograph (GC).

If using helium as carrier gas, increase the pressure to 90 psig (6.2 barg).
•
If using hydrogen as carrier gas, increase the pressure to 60 psig (4.1 barg).
