Gas chromatograph Working Animation

• The sample gas will be taken from the Process pipe line through GC Sampling system.
• A carrier gas (generally Helium) will be used to carry out the collected sample gas through the GC column.
• The GC Column will be maintained at a standard temperature (85 deg c, changes from vendor to vendor) with the heater.
• The sample gas will be heated for a certain time in the column. So that all components in the sample gas will be separated in the column.
• The separated components will travel from column to the detector individually.
• The detector will detect the respective component voltage.
• Thus finally we measure all individual components in the sample gas.
• We plot all measured components in a graph called chromatogram.
