Natural Gas Analyzer B and B Extended Version
Agilent 990 Micro GC User Manual 157
Analysis of a sample containing neo-pentane results in a chromatogram similar to Figure 83.
Analysis of a sample containing hydrocarbons up to n-nonane results in a chromatogram similar
to Figure 84.
For samples that contain hydrocarbons up to n-nonane, increase the total run time to detect all
hydrocarbons on this channel.
