Primesep 100 is a reverse-phase analytical column with embedded acidic ion-pairing groups
- This is the most versatile column of the entire Primesep family for separation of a broad range of compounds.
- Improves retention of basic compounds by cation-exchange mechanism.
- Separates acids by ion-exclusion mechanism.
- Retains neutral compounds by reverse-phase mechanism.
- All mobile phases are LC-MS and preparative chromatography compatible.
