Normal Phase Chromatography
Using Normal Phase Solvents:
Most retained compounds are most polar.
Least retained compounds are less polar.
More Non Polar Solvents make compounds retain longer.

Reverse Phase Chromatography
Using Reverse Phase Solvents:
Most retained compounds are least polar.
Least retained compounds are most polar.
More Polar Solvents (water) Make compounds retain longer.

Aqueous Normal Phase Chromatography
Using Reverse Phase Solvents:
Most retained compounds are most polar.
Least retained compounds are less polar.
More Non Polar Solvents make compounds retain longer.
