ReproSil 70 SCX is an ion-exchange HPLC column from Dr. Maisch HPLC GmbH, packed with ultra-pure, fully porous spherical silica (70 Å pore size) functionalized with sulfonic acid (–SO₃H) groups. This modification provides strong cation exchange (SCX) properties, enabling robust and selective retention of basic and positively charged analytes, particularly small molecules, amines, alkaloids, and cationic metabolites. The 70 Å pore size makes this phase especially suitable for low-molecular-weight analytes, while the strong cation-exchange functionality ensures high capacity, reproducible retention, and stable performance in aqueous buffer systems.
ReproSil 70 SCX from Dr. Maisch HPLC GmbH delivers strong ion-exchange performance with high reproducibility – the ideal column for laboratories focused on small-molecule analysis and basic compound separations.
