One of the mysteries of the English language finally explained.
The separation of a mixture by passing it in solution or suspension or as a vapor (as in gas chromatography) through a medium in which the components move at different rates.
- ‘Using high pressure liquid chromatography, the alkaloids can be purified and crystallized.’
- ‘Both blood and urine screening tests use thin layer chromatography to separate the amino acids present.’
- ‘Amino acid analyses were carried out by ion exchange chromatography on sulphonated polystyrene resin linked to divinyl benzene.’
- ‘If the stationary phase is solid, the separation process is called adsorption chromatography.’
- ‘Metabolites of gylcolysis and the citrate cycle were measured by ion chromatography coupled to mass spectrometry (IC-MS).’
1930s: from German Chromatographie (see chromato-, -graphy), early separations being displayed as a number of colored bands or spots.
