SPE polypropylene column CHROMABOND ® HR-XCW, 3 ml, 500 mg

Optimized for controlled laboratory processes, Spe Polypropylene Column Chromabond® Hr-Xcw offers an excellent solution within the ion exchangers for the SPE category. This open tubular syringe-shaped column features a hydrophobic spherical polystyrene-divinylbenzene copolymer (PS/DVB) with carboxylic acid modification, functioning as a weak mixed mode cation exchanger (WCX). With a specific surface area of 850 m²/g, it is ideal for the separation of basic active ingredients from strongly matrix-contaminated samples such as urine, plasma, serum, and strong bases with pKa >10. Its recommended storage temperature at RT ensures its long-term viability. Complementary items for your chromatography lab can be found on our dedicated Chromatography page.
