Weakly basic secondary and tertiary ammonium polymeric anion exchanger for SPE
Features
- 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 application:
- perfluorinated surfactants, acidic compounds like sulfonates, active ingredients from strongly matrix-contaminated samples like, e.g., urine, plasma, serum
- strong acids with pKa < 1
