GLC is to a great extent more widely used than GSC. During a GC separation, the sample is vaporized and carried by the mobile gas phase (i.e., the carrier gas) through the column. Separation of the different components is achieved based on their relative vapor pressure and affinities for the stationary phase.

In gas-liquid chromatography, the mobile phase is a gas such as helium and the stationary phase is a high boiling point liquid adsorbed onto a solid. How fast a particular compound travels through the machine will depend on how much of its time is spent moving with the gas as opposed to being attached to the liquid in some way.

Principle of gas chromatography. All chromatography have one stationary and one mobile phase. In this chromatography the mobile phase is always gas. But the stationary phase is either liquid or solid. If the stationary phase is solid, then that is called gas-solid chromatography or GSC. And if the stationary phase is liquid, then that is called gas-liquid chromatography or GLC.

Gas liquid Chromatography Principle of Operation • Gas liquid chromatography runs on the principle of partition. • In GLC the components of vaporize samples are fractionated due to partition between a gaseous mobile phase and a liquid stationary phase held in column.

mobile phase may be a liquid (liquid–solid chromatography) or a gas (gas–solid chromatography); the components distribute between the two phases through a combination of sorption and desorption processes. TLC is a special example of sorption chromatography in which the stationary phase is a plane, in the form of a solid

Gas chromatography principles. Image 3: The image above shows how gas chromatography works (diagram). The sample solution is placed into the gas chromatograph and enters the gas stream which transports the sample into the column (separation tube). A carrier gas is used in the form of helium or nitrogen.

A gas chromatograph (GC) is an analytical instrument that measures the content of various volatile components in a sample. The analysis performed by a gas chromatograph is called gas chromatography. Principle of gas chromatography: The sample solution injected into the instrument enters a gas stream which transports the sample into a separation tube known as the "column."
