SPE polypropylene columns ROTI ® X Bond PRS, 1 ml, 100 mg, 100 unit(s)

Widely applied in chemical workflows, Spe Polypropylene Columns Roti ® X Bond Prs are open tubular syringe-shaped columns filled with silica gel modified with propylsulfonic acid, serving as a very strong cation exchanger (SCX). These columns offer high recovery rates for pyridinic compounds due to their simple retention mechanism, which eliminates nonpolar interactions. Unlike other SCX phases, PRS does not exhibit π-π interactions, providing a unique selectivity that makes it an ideal alternative when non-polar components in samples cannot be removed using traditional SCX methods. With a pH stability range of 2.0-8.0, these columns are suitable for a variety of applications involving weak cations such as drugs and their metabolites, basic pollutants like malachite green, gentian violet, tetrodotoxin, and meth
