|See also gas chromatography the technique of separating and analysing the components of a mixture of liquids or gases by selective adsorption in, for example, a column of powder (column chromatography) or on a strip of paper (paper chromatography)|
chromatography chro·ma·tog·ra·phy (krō'mə-tŏg'rə-fē)
Any of various techniques for the separation of complex mixtures that rely on the differential affinities of substances for a gas or liquid mobile medium and for a stationary adsorbing medium through which they pass, such as paper, gelatin, or magnesia. Also called absorption chromatography.
|chromatography (krō'mə-tŏg'rə-fē) Pronunciation Key
A technique used to separate the components of a chemical mixture by moving the mixture along a stationary material, such as gelatin. Different components of the mixture are caught by the material at different rates and form isolated bands that can then be analyzed.
