Description
Modern spherical polymer for the highest demands in solid phase extraction. PS/DVB copolymer with secondary and tertiary ammonium modification for mixed-mode SPE with weak anion exchange and RP properties (WAX). Exchange capacity ≥ 0.8 meq/g, pKs 6 + 9. High-purity material with ideal flow properties and enables maximum reproducibility with extremely low blank values thanks to an optimized production process. Particularly suitable for PFAS analysis, e.g. according to EPA 533, Draft 1633 and ISO 21675:2019.
