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 section
4.2.5.3 on page 4-13.
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 Figure 8-29.

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.
