Gas chromatography- definition,principle,working,uses

Jul 11,2020· Gas chromatography differs from other forms of chromatography in that the mobile phase is a gas and the components are separated as vapors.; It is thus used to separate and detect small molecular weight compounds in the gas phase. The sample is either a gas or a liquid that is vaporized in the injection port.

Selecting a GC Inlet Liner|American Laboratory

Introduction of gas chromatography samples typically occurs through a heated inlet containing a glass liner. The role of the inlet liner is to reproducibly transfer the sample,in a gaseous phase,to a column where the chromatographic separation occurs. Use of a proper inlet liner is critical to ensuring the best possible chromatography.
