Anion Exchange Columns
Packed with non-porous resin particles, these columns enable high speed and high resolution analysis, as well as isolation, of biomolecules.
Anion Exchange Chromatography is performed with either a strong anion-exchange column, containing a quaternary ammonium ion, or with a weak anion-exchanger, having either a tertiary or secondary amine functional group, such as DEAE (diethylaminoethyl). A counter ion, often Cl-, maintains electroneutrality.
