SPE polypropylene columns ROTI ® X Bond WCX, 6 ml, 500 mg, 30 unit(s)

Produced to ensure dependable processing results, Spe Polypropylene Columns Roti ® X Bond Wcx belong to the ion exchangers for the SPE category within the broader chromatography labware. These open tubular syringe-shaped columns with Luer tip outlets are made of PP material with PE filter elements, offering a specific surface area of 600 m²/g as per BET. Filled with 500 mg of carboxylic acid-modified spherical polystyrene/divinylbenzene copolymer, they function as a weak acidic cation exchanger (mixed mode), making them ideal for the enrichment of strong basic analytes (pKa >10) in samples such as urine, plasma, and serum. With a pH stability range of 1.0-14.0, these columns offer versatile applications while maintaining
