- Separate organic acids and weak acid anions
- Polymer-based for broad pH stability
- Economical choice for small inorganics
Anion Exclusion Columns separate organic acids and weakly ionized anions by an anion exclusion mechanism. Dilute mineral acids are the typical mobile phases for the separation. Acetonitrile may be used as an organic modifier to decrease the retention of hydrophobic compounds.
