10 Micro GC Biogas Analyzers
CP Sil 5 CB channel
CP Sil 5 CB channel
The CP-Sil 5 CB channel of the Biogas Analyzer Extended is used to analyze the hydrocarbon up to
n-heptane. Hydrocarbons that are specified for this analyzer are i-butane, n-butane, neo-pentane,
n-pentane, iso-pentane, n-hexane, and n-heptane. The Universal Gas Calibration Standard does not
contain all these hydrocarbons. A reference chromatogram is included in this manual for the
missing components.
Analyzing the Universal Gas Calibration Standard with the CP-Sil 5 CB results in the
chromatogram shown in
If a hydrocarbon mixture up to n-hexane is used, the chromatogram resembles
