| General description: | Retention Mechanism: Anion-exchange Sample Matrix Compatibility: Organic or aqueous solutions • A polymerically bonded quarternary amine that remains positively charged at all pH levels • Counter ion is Cl- • Ion exchange capacity is ∼ 0.14 meq/g • Commonly used when extracting weaker anions (e.g., carboxylic acids) that may not bind strongly enough to weaker anion-exchangers • Selectivity can be modified by changing the counter ion with the appropriate buffer during conditioning |
