Analysis of the Universal Gas Calibration standard results in a
chromatogram similar to Figure 5.
Analysis of a sample containing heavier hydrocarbons up to
n-nonane results in a chromatogram similar to Figure 6.
If a sample contains hydrocarbons up to n-nonane ensure that
the total run time is increased sufficiently to detect all
hydrocarbons on this channel.
