chromatography(redirected from gel-permeation chromatography)
Also found in: Medical, Encyclopedia, Wikipedia.
Any of various techniques for the separation of complex mixtures that rely on the differential affinities of substances for a mobile (gas or liquid) medium and for a stationary adsorbing (liquid or solid) medium through which they pass, such as paper, gelatin, or silica.

1. (Chemistry) 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). See also gas chromatography
