Ion Exchange: Reversible chemical reaction between a solid, often one of the Ion exchange resins, and a fluid whereby ions may be exchanged from one substance to another. This technique is used in water purification, in research, and in industry.

Ion-Exchange Chromatography

Source: Laboratory of Dr. B. Jill Venton - University of Virginia


Ion-exchange chromatography is a type of chromatography that separates analytes based on charge. A column is used that is filled with a charged stationary phase on a solid support, called an ion-exchange resin. Strong cation-exchange chromatography preferentially separates…
