Classification of Chromatographic Techniques

There are several types of chromatographic techniques. These are based on the physical principle behind the separation. These are tabulated below.

Mode of separation	Basis for separation
Adsorption chromatography	Polarity
Partition chromatography	Solubility
Ion exchange chromatography	Charge
Size exclusion chromatography	Molecular size
Affinity chromatography	Biological activity
