1.
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.
from The American Heritage® Dictionary of the English Language, 4th Edition
1.
any of various techniques for the qualitative or quantitative separation of the components of mixtures of compounds; all characterised by the use of a mobile phase (gas or liquid) moving relative to a stationary phase (liquid or solid) - the differences between the rates of migration of the compounds between the two phases effects the separation.

A treatise on colors.
2. an analytical and preparative technique for separating substances by differences in their selective adsorption to solids, by passing a liquid over the solid, to which the substances to be separated have usually been adsorbed in a preliminary step. the major variations are column chromatography, in which the substances to be separated are adsorbed to a column with any of a wide variety of adsorbing solids in powdered or granulated form; paper chromatography, in which the solids are applied as a spot at one end of a strip of absorbent paper (such as filter paper), and the liquid is percolated through the paper by capillary action; and thin-layer chromatography (tlc), which is similar to paper chromatography, but the adsorbent material is, instead of paper, a thin layer of finely powdered material, such as cellulose or silica, on a backing of glass or plastic, called a tlc plate. A modern version of column chromatography is high-performance liquid chromatography, usually referred to as HPLC.
