CHROMABOND® HR-XC


Benzenesulfonic acid modified polymeric cation exchanger for SPE

Base material spherical PS/DVB copolymer, pore size 65-75Å, particle sizes 45µm or 85µm (standard), very large specific surface 800m²/g, pore volume 1.4cm³/g, pH stability 1-14. Benzenesulfonic acid modification, exchange capacity 1.0meq/g, pKa < 1 RP capacity 300mg/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 basic analytes for standard protocol.

Recommended application: basic active ingredients from strongly matrix-contaminated samples like, e.g., urine, plasma, serum, fungicides from food, basic analytes like, e.g., amines, bases with pKa 2-10.
