General description
Retention Mechanism: Cation exchange
Sample Matrix Compatibility: Organic or aqueous solutions
Sample Matrix Compatibility: Organic or aqueous solutions
- A polymerically bonded, ethylenediamine triacetic acid phase with a pKa of 4.8
- Counter ion is Na+
- Ion exchange capacity is ∼ 0.15 meq/g
- Carries a negative charge at pH 6.8 or above
- A pH of 2.8 or below neutralizes this phase for easier elution of strong cationic analytes that are neutralized only at extreme basic conditions
- Typically used when dealing with very strong cationic (high pKa) compounds that may be irreversibly retained on strong cation exchangers
