Electrophoresis vs. Chromatography

Electrophoresisnoun

(electricity) the migration of electrically charged molecules through a medium under the influence of an electric field

Electrophoresisnoun

(analytical chemistry) (biochemistry), a method for the separation and analysis of large molecules (such as proteins) by migrating a colloidal solution of them through a gel; gel electrophoresis

Electrophoresisnoun

the motion of charged molecules or particles in a liquid medium under the influence of an electric field; particles with a positive charge move toward the cathode and negative to the anode.

Electrophoresisnoun

the application of the principle of electrophoresis to separate molecules, used as an analytical or preparative technique; as, separation by electrophoresis; gel electrophoresis.

Electrophoresisnoun

the motion of charged particles in a colloid under the influence of an electric field; particles with a positive charge go to the cathode and negative to the anode

Electrophoresis

Electrophoresis (from the Greek meaning ) is the motion of dispersed particles relative to a fluid under the influence of a spatially uniform electric field. Electrophoresis of positively charged particles (cations) is sometimes called cataphoresis, while electrophoresis of negatively charged particles (anions) is sometimes called anaphoresis.

Chromatographynoun

(analytical chemistry) 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.

Chromatographynoun

A treatise on colors

Chromatographynoun

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.

Chromatographynoun

a process used for separating mixtures by virtue of differences in absorbency

Chromatography

Chromatography is a laboratory technique for the separation of a mixture. The mixture is dissolved in a fluid (gas or solvent) called the mobile phase, which carries it through a system (a column, a capillary tube, a plate, or a sheet) on which is fixed a material called the stationary phase.
