Structured to assist in consistent experimental procedures, the Spe Polypropylene Column Chromabond ® Hr-Xcw is designed as an ion exchanger for Solid Phase Extraction (SPE), specifically categorized under this labware category. This open tubular syringe-shaped column with Luer tip outlet features a hydrophobic spherical polystyrene-divinylbenzene copolymer (PS/DVB) with carboxylic acid modification, forming a weak mixed mode cation exchanger (WCX). Its recommended applications include the extraction of basic active ingredients from strongly matrix-contaminated samples such as urine, plasma, serum, and strong bases with pKa values greater than 10. With a specific surface area of 850 m²/g, it offers excellent separation principles through its mixed mode (RP and Ion Exchange (IEX
