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
