Primesep SB is a reverse-phase analytical column with strong embedded basic ion-pairing groups.

• Improves retention of acidic compounds by anion-exchange mechanism.
• Separates bases by ion-exclusion mechanism.
• Retains neutral compounds by reverse-phase mechanism.
• All mobile phases are LC-MS and preparative chromatography compatible (working pH range from 1.5 to 5).
