SiELC Primesep 200 is a mixed-mode HPLC column with weak acidic ion-pairing groups embedded into long ligand chains. It provides enhanced retention of strong basic compounds through a cation-exchange mechanism, retains neutral compounds by a reversed phase mechanism, and provides an additional interaction with polar molecules, enabling separation of isomers and structurally related compounds.
Features
- Primesep 200 is a mixed-mode column with weak acidic ion-pairing groups embedded into long ligand chains
- Enhances retention of strong basic compounds through cation-exchange mechanism
- Retains neutral compounds by reverse-phase mechanism
- Provides an additional interaction with polar molecules, enabling separation of isomers and structurally-related compounds
