Widely applied in chemical workflows, Spe Cartridges Chromafix ® Hr-Xc, Hr-Xc, 0.8 Ml, Medium fall under the ion exchangers for the SPE category. These tubular syringe-shaped cartridges with Luer tip inlet and outlet are made of PP columns with PE filter elements, offering a robust solution for solid phase extraction of small sample volumes. They feature hydrophobic spherical polystyrene-divinylbenzene copolymer (PS/DVB) with benzenesulfonic acid modification, making them a very strong mixed mode cation exchanger (MCX). Suitable for amines, bases with pKa 2-10, basic active ingredients from strongly matrix-contaminated samples such as urine, plasma, serum, basic analytes, fungicides from food
