The principle of column chromatography is:

Options

  1. ADifferential adsorption of the substances on the solid phase.
  2. BDifferential absorption of the substances on the solid phase.
  3. CGravitational force.
  4. DCapillary action

Correct answer

A. Differential adsorption of the substances on the solid phase.

Step-by-step solution

Principal of chromatography is based on adsorption of the substance on the solid phase. A Chromatography column is a device used in chromatography for the separation of chemical compounds. A chromatography column contains the stationary phase, allowing the mobile phase to pass through it. Chromatography columns of different types are used in both gas and liquid chromatography.
