WebIon-exchange chromatography: solid (cationic or anionic resin) liquid: ionic charge of the molecules: molecules possessing the opposite charge as the resin will bind tightly to the resin, and molecules having the same charge as the resin will flow through the column and elute out first. Affinity chromatography WebChromatography involves taking some kind of mixture and using either solid or liquid to separate it out into its different parts. There are many different kinds of chromatography, but they all rely on having a mobile phase and a stationary phase. Let's go over how paper chromatography works, since this is the simplest kind.
