Gas chromatography - Wikipedia
Gas chromatography is the process of separating compounds in a mixture by injecting a gaseous or liquid sample into a mobile phase, typically called the carrier gas, and passing the gas through a stationary phase. The mobile phase is usually an inert gas or an unreactive gas such as helium, argon, nitrogen or hydrogen. [1] .
Gas Chromatography – Principle, Application, Procedure and …
2022年3月7日 · It is a term used to describe analytical separation methods used to check volatile substances in their gas phase. What happens during gas chromatography is that the components of a sample are dissolved in a solvent and vaporized to separate the analytes. It is made possible by distributing the sample into two phases:
