Agilent Technologies 490 Micro GC User Manual

Checkout Information 2
Natural Gas Analyzers 9
More detailed information about the NGA Gas Calibration
standard and the Universal Gas Calibration standard can be
found in Appendix A on page 27 and Appendix B on page 28.
The components specified for each channel are described in
“Agilent 490 Micro GC - Natural Gas Analyzer A and the
Extended Version” on page 6 and “Agilent 490 Micro GC -
Natural Gas Analyzer B and the Extended Version” on page 7.
The NGA Gas Calibration standard and the Universal Gas
Calibration standard are shipped with the analyzer and used by
the Agilent Customer Engineer at installation. The factory
tuned method, final chromatogram (Test Report), and the
Natural Gas Analyzer User Manual are supplied on the Analyzer
CD.
To perform reference checks on the analyzer, use the NGA Gas
Calibration standard or the Universal Gas Calibration standard.
If OpenLAB CDS EZChrom is used, load the method from the
analyzer CD or create a method using the settings from the
method pdf-file available on the analyzer CD. For a quick start,
see the method settings for Natural Gas Analyzers listed in
Appendix C on page 29. Connect and inject the NGA Gas
Calibration standard.
To analyze helium on the CP-Molsieve 5A channel, use the
Universal Gas Calibration standard for the checkout. Ensure
that the carrier gas argon is supplied and configured before
starting the analysis. For more information on how to configure
the carrier gas for the analyzer see Appendix D on page 31.
Method settings for this analysis can be found in Appendix E on
page 35.
The NGA Gas Calibration standard and the Universal Gas
Calibration standard do not contain hydrogen sulfide. A
reference chromatogram of hydrogen sulfide is included in this
manual.
