Name: Anion Exchange Chromatography
Description:Anion exchange chromatography is practiced with either a strong or a weak anion exchange column, containing a quarternary ammonium ion, or with a weak anion exchanger, having either a tertiary or secondairy amine functional group, such as DEAE(diethylaminoethyl). A counter ion, often Cl- maintains electroneutrality.
Name: Cation Exchange Chromatography
Description:Cation exchange chromatography is practiced with either a strong or a weak cation exchange column, containing a sulfonium ion, or with a weak cation exchanger, having usually a carboxymethyl(CM) functional group. A counter ion, often Na+ maintains electroneutrality.
