SPE columns, CHROMABOND HR-XAW, 85 µm, 3 mL/500 mg AlkylPAHs 50 µg/mL (as sulfate)State of the art spherical polymer for highest demands in solid phase extraction. PS DVB copolymer with secondary and tertiary ammonium modification for mixed mode SPE with weak anion exchange and reversed phase properties (WAX). Exchange capacity > 0. 5 meq g, pKa ~ 6 and RP capacity 350 mg g (caffeine in water). High purity material with ideal flow properties and highest reproducibility. Allows highest reproducibility with extremely low blind values
