Weakly Basic Secondary and Tertiary Ammonium Polymeric Anion
Exchanger for SPE

Properties:

  • Base material spherical PS/DVB copolymer, pore size 55-65 Å, particle sizes 45 µm or 85 µm (standard)
  • Very large specific surface 850 m2/g, pore volume 1.2-1.4 cm3/g, pH stability 1-14
  • Secondary and tertiary ammonium modification, exchange capacity > 0.5 meq/g, pKa ~ 6
  • RP capacity 350 mg/g (caffeine in water)
  • High-purity material, highest reproducibility and lowest blank values due to an optimized production process
  • Outstanding recovery rates especially for the enrichment of acidic analytes

Recommended Applications:

  • Perfluorinated surfactants
  • Acidic compounds like sulfonates
  • Active ingredients from strongly matrix-contaminated samples like urine, plasma, serum
  • Strong acids with pKa < 1
