chro·ma·tog·ra·phy  (krm-tgr-f)
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.

chroma·togra·pher n.

chromatography (ˌkrəʊməˈtɒɡrəfɪ)
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
ˌchromaˈtographer n chromatographic adj ˌchromatoˈgraphically adv
chro•ma•tog•ra•phy (ˌkroʊ məˈtɒg rə fi)

a technique for identifying the components of chemical mixtures separated by preferential adsorption on an adsorbent medium, as a column of silica, a strip of filter paper, or a gel.
[1935–40; < German Chromatographie (1906); see chromato-, -graphy]
chro`ma•tog′ra•pher, n.
chro•mat•o•graph•ic (krəˌmæt əˈgræf ɪk) adj.
chro`ma•to•graph′i•cal•ly, adv.

chromatography  (krm-tgr-f)
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.

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.
