CHROMATOGRAPHY
| Pronunciation (US): |  | (GB): | |
I. (noun)
Sense 1
Meaning:
A process used for separating mixtures by virtue of differences in absorbency
Classified under:
Nouns denoting natural processes
Hypernyms ("chromatography" is a kind of...):
action; activity; natural action; natural process (a process existing in or produced by nature (rather than by the intent of human beings))
Hyponyms (each of the following is a kind of "chromatography"):
column chromatography (chromatography that uses selective adsorption by a column of powders)
paper chromatography (chromatography that uses selective adsorption on a strip of paper)
Derivation:
chromatographical (of or relating to chromatography)
Context examples:
Frequently referred to simply as HPLC, this form of column chromatography is used frequently in biochemistry.

A type of chromatography in which separation of a mixture is achieved by passing a sample in a stream of liquid solvent through some form of material that will provide resistance by virtue of chemical interactions between the components of the sample and the material.
(Liquid Chromatography, NCI Thesaurus)
This species is urease, nitrate reduction, Tween 80 hydrolysis, and arylsulfatase positive, acid-fast, does not produce acid from glucose, mannitol or sorbitol, but it does produce a distinctive lipid on chromatography appearing dense and brown.

LC/MS is a hyphenated technique, combining the separation power of liquid chromatography (LC), an analytical chromatographic technique for separating ions or molecules dissolved in a solvent, with the detection power of mass spectrometry(MS), a technique to separate gas phase ions according their m/z (mass to charge ratio) value.
