Suitable for laboratory and industrial environments, Spe Polypropylene Columns Roti ® X Bond Pfas are ion exchangers within the Solid Phase Extraction (SPE) category, specifically designed for the enrichment of Per- and Polyfluoroalkyl Substances (PFAS). These columns feature a hydrophobic spherical polystyrene-divinylbenzene copolymer (PS/DVB) with secondary and tertiary ammonium modification, making them a mixed mode anion exchanger (WAX). They offer a specific surface area of 600 m²/g as determined by the Brunauer-Emmett-Teller (BET) method, ensuring efficient separation principles through a combination of Reversed Phase (RP) and Ion Exchange (IEX). The columns come pre-filled with 200 mg of material and are available in packs
