gas chromatography Insights

What is gas chromatography?

Gas chromatography (GC) is an analytical technique used to separate and analyze volatile substances in a sample. The sample is vaporized and carried by an inert carrier gas through a column containing a stationary phase. Different components of the sample interact differently with the stationary phase, causing them to elute from the column at different times. These components are then detected as they exit the column, allowing for identification and quantification. GC is commonly used in environmental monitoring, food analysis, and forensic science, and in industrial settings to test the purity of materials.

What other technologies are related to gas chromatography?

gas chromatography Competitor Technologies

atomic absorption

Atomic absorption spectroscopy (AAS) is an alternative technique used for elemental analysis. Although it serves a similar purpose, it does not involve separation of a mixture prior to analysis like GC.

liquid chromatography

Liquid chromatography (LC) separates compounds in a liquid mobile phase, whereas GC uses a gas mobile phase. LC is used for compounds that are not volatile or thermally stable, and thus cannot be separated by GC.

high performance liquid chromatography

High-performance liquid chromatography (HPLC) is a type of liquid chromatography that uses high pressure to force the liquid mobile phase through a column. It is used for compounds that are not volatile or thermally stable, and thus cannot be separated by GC.
