Natural Gas Analyzers 16
8 meter CP-Sil 5 CB
The 8 meter CP-Sil 5 CB channel of the Natural Gas Analyzer A
Extended is used for the analysis of hydrocarbons from
n-hexane up to n-dodecane.
The NGA Gas Calibration standard and the Universal Gas
Calibration standard do not contain heavy hydrocarbons up to
n-dodecane. Reference chromatograms of the NGA Gas
Calibration standard and the Universal Gas Calibration
standard are included in this manual. For heavy hydrocarbons
up to n-dodecane an additional sample is analyzed for
identification.
Analysis of the NGA Gas Calibration standard results in the
chromatogram shown in Figure 12.
Reference check of the Universal Gas Calibration standard
results in a chromatogram similar to Figure 13.
