उत्तर
Chromatography is the technique used for separation of the components of a mixture that are soluble in the same solvent and are differently adsorbed on an adsorbent. This technique was first used for separation of colours and hence, the name. There are two phases in chromatography - the stationary phase and the mobile phase. The components of the mixture are absorbed differently in the stationary phase, thus leading to their separation. There are many different types of chromatography - paper chromatography, thin-layer chromatography, gas chromatography etc.
