chro·ma·tog·ra·phy

 (krō′mə-tŏg′rə-fē)
n.
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.

chro′ma·tog′ra·pher n.

chromatography

(ˌkrəʊməˈtɒɡrəfɪ)
n
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

The instrumentation for HPLC and size exclusion (SEC) or gel-permeation chromatography (GPC) is similar, but the columns differ.
Before high-pressure liquid gel-permeation chromatography (HPLGPC) [4] the specimen was treated with n-butanol (300 mL/L) to dissociate lipid- or membrane-bound enzymes.
brought out a dedicated high-temperature gel-permeation chromatography (GPC) system that uses a high-sensitivity i-r detector for analyzing a wide range of polymer molecular weights.
