Definition of chromatography in English:

chromatography

noun ˌkrəʊməˈtɒɡrəfiˌkroʊməˈtɑɡrəfi

mass nounChemistry

A technique for the separation of a mixture by passing it in solution or suspension through a medium in which the components move at different rates.
Example sentencesExamples
- If the stationary phase is solid, the separation process is called adsorption chromatography.
- Using high pressure liquid chromatography, the alkaloids can be purified and crystallized.
- Amino acid analyses were carried out by ion exchange chromatography on sulphonated polystyrene resin linked to divinyl benzene.
- Metabolites of gylcolysis and the citrate cycle were measured by ion chromatography coupled to mass spectrometry (IC-MS).
- Both blood and urine screening tests use thin layer chromatography to separate the amino acids present.

Derivatives

chromatographic

adjectiveˌkrəʊmətə(ʊ)ˈɡrafɪk

Chemistry

In the confirmatory test, the drugs in the urine sample are isolated on a small chromatographic column, eluted with an organic solvent, and injected into the gas chromatograph-mass spectrometer.
Example sentencesExamples
- During this time he developed a simple chromatographic assay for imidazole compounds accumulating in histidine-requiring Neurospora mutants, which allowed him to deduce much of the histidine biosynthetic pathway.
- Molecular fossils are recovered and studied using chromatographic techniques, mass spectrometry, and spectrophotometry.
- Once the structure of an organic species has been identified, the presence of the molecule in other samples can be detected by using spectroscopic patterns or chromatographic characteristics of the compound.
- Modern methods for measuring molecular weight include chromatographic methods and mass spectrometry.

Origin

1930s: from German Chromatographie (see chromato-, -graphy), early separations being displayed as a number of coloured bands or spots.
