Question

What is chromatography ?GIVE ME A CLEAR DEFINITION

Answer 1

Chromatography is 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. In other words, it is the collective term for a set of laboratory techniques for the separation of mixtures. The mixture is dissolved in a fluid called the mobile phase, which carries it through a structure holding another material called the stationary phase.
