Solution
Depending on the nature of the stationary phase i.e., whether it is a solid or a liquid, chromatography is classified into adsorption chromatography and partition chromatography.
- Adsorption chromatography: This technique is based on the principle of differential adsorption. Different solutes are adsorbed on an adsorbent to a different extent.
Adsorption chromatography is further classified into two types:
a. Column chromatography
b. Thin-layer chromatography - Partition chromatography: This technique is based on the continuous differential partitioning of components of a mixture between stationary and mobile phases. For example, paper chromatography.
