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).

High-purity material with ideal flow properties and highest reproducibility. Allows highest reproducibility with extremely low blind values due to an optimised production process.

Outstanding recovery rates especially for the enrichment of acidic analytes like short-chain PFAS.

Acidic analytes from various samples. Strong acids with pka <1. Per- and polyfluoroalkyl substances (PFAS) from drinking water, soil, sediment, and wastewater.
