Chromatography ( from Greek χρῶμα chroma " color " and γράφειν graphein " to write ") is the collective term for a set of laboratory techniques for the separation of mixtures.

Chromatography is based on the concept of partition coefficient.

Countercurrent Chromatography is a method of separation, that is based on the differential partitioning of analytes between two immiscible liquids using countercurrent or cocurrent flow.

Evolving from Craig's Countercurrent Distribution ( CCD ), the most widely used term and abbreviation is CounterCurrent Chromatography or CCC, in particular when using hydrodynamic CCC instruments.

This is also known as Immunoaffinity Chromatography.

Gas Chromatography, Infrared Spectrometry or Mass Spectrometry is used in combination with the color test to identify the type of drug.

Known as Hydrophilic Interaction Chromatography ( HILIC ) in HPLC, this method separates analytes based on polar differences.

Chromatography tags are used to alter chromatographic properties of the protein to afford different resolution across a particular separation technique.

Chromatography can be used to separate protein in solution or denaturing conditions by using porous gels.

Chromatography, electrophoresis and Field Flow Fractionation are representative of this field.

Chromatography may be preparative or analytical.

Chromatography, literally " color writing ", was first employed by Russian scientist Mikhail Tsvet in 1900.

Chromatography technique developed substantially as a result of the work of Archer John Porter Martin and Richard Laurence Millington Synge during the 1940s and 1950s.

There were also attempts to fractionate synthetic high polymers ; however, it was not until 1964, when J. C. Moore of the Dow Chemical Company published his work on the preparation of Gel Permeation Chromatography ( GPC ) columns based on cross-linked polystyrene with controlled pore size, that a rapid increase of research activity in this field began.
