Adsorption and distribution chromatography difference?
Adsorption Chromatography = Utilizes a mobile liquid or gaseous phase that is adsorbed onto the surface of a stationary solid phase. The equilibriation between the mobile and stationary phase accounts for the separation of different solutes.

Distribution Chromatography (aka Liquid-Liquid extraction) = Due to its liquid stationary phase, the ingredients are only separated by their respective polarity, i.e. according to their distribution coefficient KD. Distribution chromatography is also ideal for the concentration of trace quantities. This is more closely related to Flash, Column, and Gas Chromatography.
