SPE column, CHROMABOND WAX, 30 µm, 6 mL/150 mg
*taxes and shipping not included
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 ≥ 0.8 meq/g, pKa 6 + 9. High-purity material with ideal flow properties and highest reproducibility. Allows highest reproducibility with extremely low blind values due to an optimized production process. Especially suitable for PFAS analysis e.g. according to EPA 533, Draft 1633 and ISO 21675:2019. Ideal for PFAS analysis. If you have further questions, please contact us.
