Single Choice

A form of partition, adsorption, ion exchange, or affinity chromatography in which one phase is liquid (aqueous) flowing down a column packed with the second phase, a solid is called _______.

Apartition chromatography
Bcolumn chromatography
Correct Answer
Cthin layer chromatography
Dadsorption chromatography

Solution

Column chromatography is one of the most useful methods for the separation and purification of both solids and liquids. This is a solid - liquid technique in which the stationary phase is a solid & mobile phase is a liquid. The principle of column chromatography is based on differential adsorption of substance by the adsorbent.
