The simple type of chromatography is named as ___ chromatography.

Chromatography is the technique for the separation, purification, and testing of compounds. In this process, we apply the mixture to be separated on a stationary phase (solid or liquid) and a pure solvent such as water or any gas is allowed to move slowly over the stationary phase, carrying the components separately as per their solubility in the pure solvent.

The simple type of chromatography is the Paper chromatography. It is the chromatography method that uses paper strips or sheets as the adsorbent stationary phase through which a solution flows.
