SPE columns, CHROMABOND HR-XA, 85 µm, 3 mL/500 mg pH 4 5–50 mg/L NO₂⁻State of the art spherical polymer for highest demands in solid phase extraction. PS DVB copolymer with quaternary ammonium modification for mixed mode SPE with strong anion exchange and reversed phase properties (MAX). Exchange capacity 0. 25 meq g, pKa ~ 18 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 due to an
