SPE polypropylene columns ROTI ® X Bond MAX, 12 ml, 500 mg, 20 unit(s)

Recommended for applications requiring controlled solvent behavior, Spe Polypropylene Columns Roti ® X Bond Max offer a unique combination of reversed phase and strong anion exchange retention mechanisms. These open tubular syringe-shaped columns with Luer tip outlets, filled with hydrophobic spherical polystyrene-divinylbenzene copolymer (PS/DVB) with quaternary ammonium modification, are particularly effective in the enrichment of acidic analytes (pKa 2-8). With a specific surface area of 300 m²/g according to BET, these columns are ideal for separating acidic active ingredients from strongly matrix-contaminated samples such as urine, plasma, serum, and phenolic acids. They come packaged in sets of four containing five units each, with a filling quantity of 500mg per column and
