| General description: | Retention Mechanism: Cation exchange 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 |
