ABSTRACT
One instrumental chromatography configuration discussed briefly in Chapter 11 is one in which the mobile phase is a gas and the stationary phase is either a liquid or a solid. This configuration is called
gas chromatography
, known simply as GC. It is also known as either GLC (
gas-liquid chromatography
) or GSC (
gas-solid chromatography
) in order to stipulate whether the stationary phase is a liquid or a solid, respectively. Most gas chromatography procedures utilize a liquid stationary phase, or GLC, and thus the chromatography type (see Chapter 11 for the distinction between type and configuration) is partition chromatography most of the time. The only other possible type that is applicable here is adsorption chromatography. Thus, GSC refers to this latter type.
