General description
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
