Designed for professional use, the Spe Polypropylene Columns Roti ® X Bond Wcx come in a packing of 10 x 5 units, each containing 3 ml of column volume filled with 500 mg of carboxylic acid modified spherical polystyrene/divinylbenzene copolymer, a weak acidic cation exchanger (mixed mode), ideal for the enrichment of strong basic analytes (pK a >10). These open tubular syringe-shaped columns with Luer tip outlets have a specific surface area of 600 m²/g as per BET, a particle size of 40 µm, and a pore size of 300 Å. They are made of PP columns with PE filter elements and are recommended for use with strongly base active ingredients from matrix-contaminated samples such as urine, plasma
