Fast Protein Liquid Chromatography

a form of liquid chromatography that is often used to analyze or purify mixtures of proteins.

Counter Current Chromatography

a form of liquid-liquid chromatography that uses a liquid stationary phase that is held in place by centrifugal force and is used to separate, identify, and quantify the chemical components of a mixture.

Supercritical Fluid Chromatography

a form of normal phase chromatography, first used in 1962, that is used for the analysis and purification of low to moderate molecular weight, thermally labile molecules. It can also be used for the separation of chiral compounds.

Pyrolysis Gas Chromatography

a method of chemical analysis in which the sample is heated to decomposition to produce smaller molecules that are separated by gas chromatography and detected using mass spectrometry.

Affinity Chromatography

a method of separating biochemical mixtures based on a highly specific interaction such as that between antigen and antibody, enzyme and substrate, or receptor and ligand.

Column Chromatography

a method used to purify individual chemical compounds from mixtures of compounds.

High Performance Liquid Chromatography

a technique in analytical chemistry used to separate, identify, and quantify each component in a mixture.

Paper Chromatography

an analytical method used to separate colored chemicals or substances.

Gas Chromatography

chromatography employing a gas as the moving carrier medium.

Thin Layer Chromatography

compounds are separated on a thin layer of adsorbent material, typically a coating of silica gel on a glass plate or plastic sheet.

Reversed Phase Chromatography

includes any chromatographic method that uses a hydrophobic stationary phase.

Definition of Chromatography

the separation of a mixture by passing it in solution or suspension or as a vapor through a medium in which the components move at different rates.

Two Dimensional Chromatography

type of chromatographic technique in which the injected sample is separated by passing through two different separation stages.
