MediumWhat is meant by the term "chromatography"?
(N/A) Chromatography is a collective term used for a family of laboratory techniques for the separation of mixtures.
The term is derived from Greek words 'chroma' meaning 'colour' and 'graphein' meaning 'to write'.
Chromatographic techniques are based on the principle that different components of a mixture are adsorbed to different extents on a stationary phase.
There are several chromatographic techniques such as paper chromatography,column chromatography,gas chromatography,etc.
