SPE polypropylene column CHROMABOND ® HR-XA, 3 ml, 60 mg

Built to deliver predictable results in synthesis routines, the Spe Polypropylene Column Chromabond ® Hr-Xa is a versatile ion exchanger within the Solid Phase Extraction (SPE) category. This product features a strong anion exchanger phase, ideal for the enrichment of acidic analytes with a pKa range of 2-8. The open tubular syringe-shaped column with Luer tip outlet offers a 3 ml column volume filled with 60 mg of fully porous particles (FPP), ensuring optimal performance. With a specific surface area of 850 m²/g according to BET, this column delivers exceptional separation capabilities, making it suitable for applications such as the extraction of acidic active ingredients from strongly matrix-contaminated samples like urine, plasma, serum, phenolic acids, and acidic herbicides
