SPE polypropylene columns ROTI ® X Bond WAX, 3 ml, 60 mg, 50 unit(s)

Intended for structured formulation workflows, Spe Polypropylene Columns Roti ® X Bond Wax come packaged in sets of 10 x 5 units, each containing 3 ml columns filled with 60 mg of a weak mixed mode anion exchanger material. These open tubular syringe-shaped columns with Luer tip outlets feature hydrophobic spherical polystyrene-divinylbenzene copolymer (PS/DVB) particles with secondary and tertiary ammonium modifications, providing a separation principle that combines reversed phase (RP) and ion exchange (IEX) mechanisms. With a specific surface area of 600 m²/g according to BET, these columns are ideal for the enrichment of strongly acidic analytes (pKa <1), particularly for determining strong acidic pollutants such as perfluorinated car
