SPE polypropylene column CHROMABOND ® HR-XA, 3 ml, 200 mg

A reliable solution for controlled synthesis, the Spe Polypropylene Column Chromabond ® Hr-Xa offers exceptional performance as an ion exchanger for solid phase extraction (SPE). This open tubular syringe-shaped column features fully porous particles (FPP), making it ideal for the enrichment of acidic analytes with a pKa range of 2-8. With a specific surface area of 850 m²/g and a pH stability of 1.0-14.0, this column ensures optimal results across a wide range of applications, including the separation of acidic active ingredients from strongly matrix-contaminated samples such as urine, plasma, serum, phenolic acids, and acidic herbicides. Its hydrophobic spherical polystyrene-divinylbenzene copolymer (PS/DVB) with qu
