What is chromatography? State its applications.
Chromatography is the technique whereby different soluble components of a mixture are separated due to their differential movement over a stationary phase under the influence of mobile phase, i.e., solvent. If hexane is the solvent then the component that is more soluble inhexane will move faster. In this way the different components get separated.
The technique of chromatography is used to separate
(a) components of dyes
(b) pigments from natural colours
(c) amino acids
(d) sugars from urine samples
(e) drugs in blood.
