Primesep AB is a reverse-phase column with embedded acidic and basic ion-pairing groups.

• Improves retention of strong acidic compounds and strong basic compounds by ion-exchange mechanism.
• Retains neutral compounds by reverse-phase mechanism.
• All mobile phases are LC-MS and preparative chromatography compatible.
