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
(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

chro•ma•tog•ra•phy

(ˌkroʊ məˈtɒg rə fi)

n.
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.

chro·ma·tog·ra·phy

(krō′mə-tŏg′rə-fē)
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.

chromatography

1. The technique of analyzing the composition of a liquid or gas by adsorption in a medium.
2. A way of separating and identifying mixtures of solutes in a solution.
