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

Structured to assist in consistent experimental procedures, the Spe Polypropylene Columns Roti ® X Bond Wax are designed for use within the ion exchangers for the Solid Phase Extraction (SPE) category. These open tubular syringe-shaped columns with Luer tip outlets come packed with 500mg of hydrophobic spherical polystyrene-divinylbenzene copolymer (PS/DVB) particles, featuring secondary and tertiary ammonium modifications, making them a weak mixed mode anion exchanger (WAX). With a specific surface area of 600 m²/g and a particle size of 40 µm, these columns offer excellent separation capabilities for strong acids with pKa values below 1, such as sulfonates. Ideal for determining strong acidic pollutants like perfluorinated carboxylic
