1. Chromatographynoun

   (Chem.) 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.

1. chromatographynoun

   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.

1. Chromatography

   In chemical analysis, chromatography is a laboratory technique for the separation of a mixture into its components. The mixture is dissolved in a fluid solvent (gas or liquid) called the mobile phase, which carries it through a system (a column, a capillary tube, a plate, or a sheet) on which a material called the stationary phase is fixed. Because the different constituents of the mixture tend to have different affinities for the stationary phase and are retained for different lengths of time depending on their interactions with its surface sites, the constituents travel at different apparent velocities in the mobile fluid, causing them to separate. The separation is based on the differential partitioning between the mobile and the stationary phases. Subtle differences in a compound's partition coefficient result in differential retention on the stationary phase and thus affect the separation.Chromatography may be preparative or analytical. The purpose of preparative chromatography is to separate the components of a mixture for later use, and is thus a form of purification. This process is associated with higher costs due to its mode of production. Analytical chromatography is done normally with smaller amounts of material and is for establishing the presence or measuring the relative proportions of analytes in a mixture. The two types are not mutually exclusive.

1. chromatography

   Chromatography is a laboratory technique used for the separation of mixtures into their individual components. It involves passing the mixture, which is dissolved in a fluid known as the mobile phase, over a stationary phase, which separates the mixture by differential partitioning between the mobile and stationary phases. The different rates of migration create a separation of the components based on their differing affinities for the mobile phase and the stationary phase. It is commonly used in biochemistry and analytical chemistry for the separation and identification of compounds.

1. Chromatography

   Chromatography [|krəʊmə|tɒgrəfi] is the collective term for a set of laboratory techniques for the separation of mixtures. The mixture is dissolved in a fluid called the mobile phase, which carries it through a structure holding another material called the stationary phase. The various constituents of the mixture travel at different speeds, causing them to separate. The separation is based on differential partitioning between the mobile and stationary phases. Subtle differences in a compound's partition coefficient result in differential retention on the stationary phase and thus changing the separation. Chromatography may be preparative or analytical. The purpose of preparative chromatography is to separate the components of a mixture for more advanced use. Analytical chromatography is done normally with smaller amounts of material and is for measuring the relative proportions of analytes in a mixture. The two are not mutually exclusive.

1. Chromatography

   Techniques used to separate mixtures of substances based on differences in the relative affinities of the substances for mobile and stationary phases. A mobile phase (fluid or gas) passes through a column containing a stationary phase of porous solid or liquid coated on a solid support. Usage is both analytical for small amounts and preparative for bulk amounts.
