Class Information
Number: 210/656
Name: Liquid purification or separation > Processes > Chromatography
Description: Process in which a solid sorbent competes in affinity with a relatively moving carrier liquid or solvent for a constituent such that the constituent is moved through the sorbent at a rate slower than the liquid and determined by the equilibrium or partition coefficient of the liquid-sorbent combination.
