SPE polypropylene column CHROMABOND ® HR-XAW, 500 mg

Designed for professional use, the Spe Polypropylene Column Chromabond ® Hr-Xaw is a versatile ion exchanger suitable for Solid Phase Extraction (SPE). This open tubular syringe-shaped column features a weak basic anion exchanger phase, specifically designed for the enrichment of strongly acidic analytes (pKa <1), such as perfluorinated surfactants and acidic active ingredients from contaminated samples like urine, plasma, serum, and strong acids. With a specific surface area of 850 m²/g, this column offers excellent separation performance and a high capacity for cations and anions (> 0.5 meq/g). It also exhibits a robust RP capacity for caffeine in water (350 mg/g). The column's material, PP columns with PE filter elements, ensures longe
