SPE polypropylene column CHROMABOND ® HR-XCW, 1 ml, 30 mg

Structured to assist in consistent experimental procedures, the Spe Polypropylene Column Chromabond ® Hr-Xcw is designed as an ion exchanger for Solid Phase Extraction (SPE), specifically categorized under the category of 'Ion exchangers for the SPE'. This open tubular syringe-shaped column with Luer tip outlet features fully porous particles (FPP) of particle size 85 μm, filled with 30 mg of hydrophobic spherical polystyrene-divinylbenzene copolymer (PS/DVB) with carboxylic acid modification, forming a weak mixed mode cation exchanger (WCX). With a specific surface area of 850 m²/g, this column offers excellent separation principles through its mixed mode (RP and Ion exchange (IEX)) capabilities. Its recommended applications include the extraction of
