What is Gas Chromatography? : Shimadzu Scientific Instruments
2.3. Gas Chromatography Separation. Separation by GC occurs within the column. The sample containing multiple compounds is injected into the column together with the mobile phase. (In GC, the mobile phase is a gas referred to as the carrier gas. He is frequently used.) Both the sample and the mobile phase travel through the column, but the rate

Gas Chromatography: Principles, Types and Working Lab
Majorly, there are two gas chromatography types into which it is classified GLC or gas-liquid chromatography and GSC or gas-solid chromatography. Both the methods use either liquid or solid as a stationary phase while using gas as the mobile phase. In Gas-solid chromatography, the retention of analytes is due to physical adsorption.
