SPE columns, CHROMABOND HR-XC, 85 µm, 3 mL/60 mg Synonym - PFUndA 5'-TetrachlorobiphenylState of the art spherical polymer for highest demands in solid phase extraction. PS DVB copolymer with benzenesulfonic acid modification for mixed mode SPE with strong cation exchange and reversed phase properties (MCX). Exchange capacity 1. 0 meq g, pKa < 1 and RP capacity 300 mg g (caffeine in water). High purity material with ideal flow properties and highest reproducibility. Allows highest reproducibility with extremely low blind values due to an
