Chromatography Definition and Examples

Chromatography Definition and Examples Chromatography is a group of laboratory techniques to separate the components of a mixture by passing the mixture through a stationary phase. Typically, the sample is suspended in the liquid or gas phase and is separated or identified based on how it flows through or around a liquid or solid phase. Types of Chromatography The two broad categories of chromatography are liquid chromatography (LC) and gas chromatography (GC). Highs of other types of chromatography include ion exchange chromatography, resin chromatography, and paper chromatography. Uses of Chromatography Chromatography is used primarily to separate components of a mixture so that they can be identified or collected. It can be a useful diagnostic technique or part of a purification scheme.
