column gas chromatography (GC) – a column is packed with a solid or with a solid coated by a liquid, and a gas is passed through the column under pressure at high temperature. Separation depends on the balance between solubility in the moving phase AT a, i and k PS 1.2, 3.2 and 4.1 Students could use thin-layer chromatography to identify ...

Gas Chromatography-Mass Spectroscopy
cires1.colorado.eduGas Chromatography In general, chromatography is used to separate mixtures of chemicals into individual components. Once isolated, the components can be evaluated individually. In all chromatography, separation occurs when the sample mixture is introduced (injected) into a mobile phase. In liquid chromatography (LC), the mobile phase is a solvent.
