Popis

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
