Designed for professional use, the Spe Polypropylene Column Chromabond ® Hr-Xcw is available in packs of six containing five units each. This ion exchanger for solid phase extraction features an open tubular syringe-shaped column with a Luer tip outlet, filled with hydrophobic spherical polystyrene-divinylbenzene copolymer (PS/DVB) particles that have been carboxylic acid-modified, creating a weak mixed mode cation exchanger (WCX). With a specific surface area of 850 m²/g according to BET, this column offers excellent separation capabilities for basic active ingredients from strongly matrix-contaminated samples such as urine, plasma, serum, and other strong bases with pKa values greater than 10. The column's particle size is 85 µm, and it
