Description

A gas chromatograph can be used to separate not only gaseous substances, but also volatile liquids. Only the gaseous part is separated, however. In such cases, the separation column and the carrier gas can be warmed if necessary. In experiment C3.2.1.2, the gas chromatographic analysis of an alcohol mixture is carried out.
