SPE polypropylene column CHROMABOND ® HR-XAW, 200 mg

Developed to align with modern chemical standards, the Spe Polypropylene Column Chromabond ® Hr-Xaw, 200 Mg is an ion exchanger specifically designed for the Solid Phase Extraction (SPE) category. This product features a weak basic anion exchanger phase, HR-XAW, made from a hydrophobic spherical polystyrene-divinylbenzene copolymer with secondary and tertiary ammonium modification. It exhibits a mixed mode separation principle, combining reversed-phase (RP) and ion exchange (IEX), making it ideal for the enrichment of strongly acidic analytes (pKa <1), such as perfluorinated surfactants and acidic compounds like sulphonates. With a specific surface area of 850 m²/g, this open tubular syringe-shaped
