Primesep PB is a reverse-phase analytical column with embedded aromatic and basic ion-pairing groups.

Improves retention of acidic compounds by anion-exchange mechanism.

Separates aromatic compounds by difference in pi-pi interaction.

Retains neutral compounds by reverse-phase mechanism.

All phases are LC-MS and preparative chromatography compatible (working pH range from 2.0 to 5).
