Engineered for consistent performance, the Spe Polypropylene Column Chromabond ® Hr-Xaw is designed specifically for the enrichment of strongly acidic analytes (pKa <1), such as perfluorinated surfactants and acidic active ingredients from strongly matrix-contaminated samples like urine, plasma, serum, and strong acids. This ion exchanger for solid phase extraction features a hydrophobic spherical polystyrene-divinylbenzene copolymer (PS/DVB) with secondary and tertiary ammonium modification, creating a mixed mode anion exchanger (WAX) that offers excellent separation principles for RP and ion exchange (IEX). With a specific surface area of 850 m²/g, this open tubular syringe-shaped column ensures optimal sample throughput while maintaining low blanks, outstanding recovery
