Natural Gas Analyzer B and B Extended Version
PoraPLOT U
The PoraPLOT U channel of the Agilent 490 Micro GC - Natural
Gas Analyzer B and Extended version is specified for the
analysis of methane, carbon dioxide, ethane, hydrogen sulfide,
and propane in natural gas samples. The total sample path of
this channel is deactivated (Ultimetal), which results in better
performance and peak shape for hydrogen sulfide.
Analysis of the NGA Gas Calibration standard results in a
chromatogram similar to Figure 16.
