1 - Partition chromatography

2 - Normal–phase chromatography Separates based on their affinity (Close up) for a polar and non-polar stationary such as: - Silica for polar stationary - Chloroform for non-polar stationary

2 - Normal–phase chromatography

3 - Displacement chromatography Molecule with a high affinity (Close up) for the chromatography matrix

3 - Displacement chromatography

4 - Reversed-phase chromatography (RPC) has a non-polar stationary phase and moderate polar mobile phase.

5 - Size-exclusion chromatography (SEC) - gel permeation chromatography or - gel filtration chromatography Separates particles basis on molecular size
