Introduction
The Agilent 490 Micro GC - Natural Gas Analyzers are factory
tuned on carrier gas helium including appropriate settings for
back flush times for the following channels:
• HayeSep A
• 4 meter CP-Sil 5 CB
• CP-Molsieve 5A
• PoraPLOT U
The final checkout of the Agilent 490 Micro GC - Natural Gas
Analyzer is performed with a NGA Gas Calibration standard
and a Universal Gas Calibration standard.
• The NGA Gas Calibration standard contains nitrogen,
methane, ethane, carbon dioxide, propane, iso-butane,
n-butane, iso-pentane, n-pentane, and n-hexane. This natural
gas standard does not contain all components specified for
each type of Natural Gas Analyzer. Therefore, a second
checkout sample, the Universal Gas Calibration standard is
analyzed on the Natural Gas Analyzer.
• The Universal Gas Calibration standard contains helium,
neon, hydrogen, oxygen, nitrogen, methane, ethane, ethylene,
carbon dioxide, carbon monoxide, acetylene, propane,
methyl acetylene, n-butane, n-hexane, and n-heptane. Not all
components in the Universal Gas Calibration standard are
specified for the Natural Gas Analyzer.
