(analytical chemistry) Any of various techniques for the qualitative or quantitative separation of the components of mixtures of compounds; all characterised by the use of a mobile phase (gas or liquid) moving relative to a stationary phase (liquid or solid) - the differences between the rates of migration of the compounds between the two phases effects the separation.

plural of chromatography

(chemistry) A simple form of analytical chromatography in which the stationary phase is a sheet of paper.

(chemistry) A form of chromatography in which the stationary phase has pores that allow separation of molecules having different sizes and shapes

gas-liquid chromatography

(chemistry) A form of thin layer chromatography in which a stationary phase consisting of silica coated with silver nitrate is used to separate cis- and trans- fatty acid derivatives

Synonym of ion exchange chromatography

Absorbent paper used to soak up colours so that they separate out into their various components.
