General description

Retention Mechanism: Mixed-Mode Cation Exchange (reversed-phase and cation-exchange)
Sample Matrix Compatibility: Aqueous Solutions (biological fluids, water)

  • Packed bed contains both octyl (C8) & benzene sulfonic acid (SCX) bondings
  • Dual retention mechanism broadens retention for a range of neutral, basic, acidic and zwitterionic compounds
  • Developed for superior selectivity/ sample clean up when isolating basic compounds from biological fluids
  • Greater ion-exchange capacity for isolating polar basic and zwitterionic compounds
  • Can be used to fractionate basic/ zwitterionic compounds from acidic and neutral compounds
