Difference Between Adsorption Chromatography And Partition Chromatography?

 Adsorption Chromatography

• Based on the fact that different compounds are adsorbed on an adsorbent to different degrees

• Commonly used adsorbents − Silica gel and alumina

• A mobile phase is allowed to move over a stationary phase (adsorbent). Then the components of the mixture move by varying distance over the stationary phase.

Partition Chromatography

• Based on continuous differential partitioning of components of mixture between stationary and mobile phases

• Paper chromatography is a type of partition chromatography.

• For paper chromatography, chromatography paper (a special type of paper) is used which contains water trapped in it and acts as the stationary phase.

• The chromatography paper retains different components according to their differing partition in the two phases.

• The developed paper is called chromatogram
