Gas Solid Chromatography vs. Gas Liquid Chromatography: What's the Difference?

Edited by Huma Saeed || By Sumera Saeed || Published on January 3, 2024
Gas solid chromatography separates compounds using a solid stationary phase, while gas liquid chromatography uses a liquid stationary phase.

Key Differences

Gas Solid Chromatography (GSC) involves a stationary phase that is solid, typically a granular material. Gas Liquid Chromatography (GLC), however, uses a liquid stationary phase coated on a solid support.

In GSC, the separation of components is based on their adsorption to the solid surface. In GLC, the separation occurs due to the differing solubilities of compounds in the liquid phase.

Gas Solid Chromatography is often used for gases or volatile compounds that do not interact chemically with the solid phase. Gas Liquid Chromatography is more versatile and can be used for a wider range of compounds, including those that are less volatile.
