Developed to align with modern chemical standards, the Spe Polypropylene Column Chromabond ® Hr-Xc is an ion exchanger designed specifically for the Solid Phase Extraction (SPE) category within the broader field of chromatography. This product features a unique hydrophobic spherical polystyrene-divinylbenzene copolymer (PS/DVB) with benzenesulfonic acid modification, making it a very strong mixed mode cation exchanger (MCX), ideal for the enrichment of basic analytes with a pKa ranging between 2 and 10. With a specific surface area of 800 m²/g, this open tubular syringe-shaped column offers exceptional separation capabilities while maintaining low blanks, outstanding recovery rates, and high reproducibility. Its recommended applications include the extraction of basic active ingredients from strongly matrix-
