| CHROMABOND® HR-XC The innovative cation exchanger offers: mixed-mode SPE phase with distinct cation exchange and RP properties excellent enrichment of basic analytes modern support polymer with optimised pore structure and large specific surface good reproducibility, reliable and cost-efficient analyses more aggressive washing procedures for matrix removal possible cleaner samples and protection of analytical HPLC and GC instrumentation quantificationof analytes from heavily contaminated samples lower limits of detection also for critical matrices ... the perfect fit for basic analytes in comination with CHROMABOND® HR-X 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 1.4cm≥/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.
