Engineered for consistent performance, the Spe Polypropylene Column Chromabond ® Hr-Xc is designed for the enrichment of basic analytes with a pKa range of 2-10. This ion exchanger, part of the Solid Phase Extraction category, features fully porous particles (FPP) with a hydrophobic spherical polystyrene-divinylbenzene copolymer (PS/DVB) surface that has been modified with benzenesulfonic acid, creating a very strong mixed mode cation exchanger (MCX). With a specific surface area of 800 m²/g, this open tubular syringe-shaped column offers excellent separation principles through its mixed mode (RP and Ion exchange (IEX)) capabilities. The column's particle size of 85 µm, combined with its filling quantity of 2
