Definitions and meanings of "Chromatography"

What do we mean by chromatography?

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. noun

A treatise on colors. noun

A treatise on colors. noun

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. noun

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. noun

A process used for separating mixtures by virtue of differences in absorbency noun

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.
