Primesep B2 is a reverse-phase analytical column with 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 7).
Primesep B2 columns are available in all standard dimensions
