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.

Introduction to Liquid Chromatography
www.chem.tamu.eduWhat is Chromatography? Separation of a mixture into individual components. The separation uses a Column (stationary phase) and Solvent (mobile phase). The components are separated from each other based on differences in affinity for the mobile or stationary phase. The goal of the separation is to have the best
