11 Micro GC Natural Gas Analyzer
Natural Gas Analyzer B and B Extended Version
Agilent 990 Micro GC User Manual 159
The CP-Molsieve 5A channel is factory tuned on carrier gas helium. If analysis of helium or
hydrogen is required on the CP-Molsieve 5A channel, the carrier gas must be changed and
configured for argon.
Analysis of the Universal Gas Calibration standard results in a chromatogram similar to Figure 87.
For tuning the backflush time, please refer to Tuning the backflush time on a HayeSep A
channel on page 78.
