Developed to align with modern chemical standards, the Spe Cartridges Chromafix® Hr-Xc, Hr-Xc (S), 0.4 Ml, Small, serve as efficient ion exchangers within the Solid Phase Extraction (SPE). These tubular syringe-shaped cartridges, made of polypropylene (PP) with polyethylene (PE) filter elements, cater to the separation principles of mixed mode, combining reversed-phase and ion exchange mechanisms. They exhibit a specific surface area of 800 m²/g, ensuring high efficiency in their intended applications. Suitable for handling small sample volumes, these cartridges boast a column volume of 0.4 ml, a particle size of 85 µm, and a pore size of 65-75 Å. Their hydrophobic spherical polystyrene-div
