8.3.2 Running a Low Pressure, Clean Gas Sample
To obtain a low pressure, clean gas sample, use the standard 10 micron sample
inlet filter assembly for filtration (PN G2801-60900, included in the ship kit).
1
Turn 3000 Micro GC on.
2
Make sure the carrier gas supply is sufficient to run all of the samples.
3
If using a sample vessel, prepare the sample.
NOTE: If not installed, install the sample inlet filter assembly. Refer to
.
4
Connect the sample container or gas source to the 3000 Micro GC sample
inlet.
NOTE: For sample source pressures above 172 kPa (25 PSI), install a pressure
regulator as shown in
.

5
Open the sample vessel valve, and adjust the pressure to <172 kPa (<25 PSI).
6
Use EZ IQ software to load the desired method and perform the analysis.
7
When the analysis is complete, close the sample vessel valve and disconnect
the vessel from the instrument.
8
Repeat steps 3 to 7 to run the next sample.
