Helix Chromatography / Coresep
Coresep
Coresep columns are mixed-mode phases on core-shell particles. Thus, these columns combine the unique selectivity of mixed-mode phases with the efficiency of core-shell particles.
Technical Data
| Phase | Modes | Particle size / μm | Pore size / Å |
| Coresep 100 | Reversed phase
| 2.7 | 90 |
| Coresep S | HILIC
| 2.7 | 90 |
| Coresep SB | Reversal phase
| 2.7 | 90 |
Coresep 100
- reversed phase column with embedded acidic ion-pairing groups
- improved retention of basic compounds by cation-exchange
- separates acidic compounds by ion exclusion
- retains neutral compounds by reversed phase
Coresep S
- normal phase column with embedded acidic ion-pairing groups
- suitable for separation of sugars and other neutral or very polar compounds
- separate compounds based on HILIC, cation-exchange and anion-exclusion
- separates acidic compounds by ion exclusion
- separate weak bases by ion-exchange
Coresep SB
- reversed phase column with strong embedded basic ion-pairing groups
- separate bases by ion-exclusion
- retains neutral compounds by reversed phase
