SPE Cartridges CHROMAFIX ® HR-XCW, 0.4 ml, Small

Recommended for applications requiring controlled solvent behavior, such as basic active ingredient isolation from strongly matrix-contaminated samples like urine, plasma, or serum, Spe Cartridges Chromafix® Hr-Xcw offers a reliable solution. These small tubular syringe-shaped cartridges feature hydrophobic spherical polystyrene-divinylbenzene copolymer (PS/DVB) with carboxylic acid modification, making them a weak mixed mode cation exchanger (WCX). With a specific surface area of 850 m²/g, they provide excellent separation capabilities while maintaining high exchanger capacities (> 0.7 meq/g). Their pH stability ranges from 1.0 to 14.0, ensuring versatile applicability. Store these Spe Cartridges Chromafix® Hr-Xcw at
