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
