SunShell PFP&C18 2.6 μm
Sunniest PFP&C18 5 μm
hydrophobicity to PFP separation!
Increased retention and improved durability
Comparison of separation
Compared to PFP, PFP & C18 has the same stereoselectivity, but the hydrophobicity is greatly increased and the retention time is extended. PFP & C18 has achieved the same separation as that of PFP, such as the separation of fluorobenzenes.
| Hydrogen bond (Caffeine/Phenol) | Hydrophobicity (Amylbenzene/Butylbenzene) | Steric selectivity (Triphenylene/o-Terphenyl) | |
| PFP | 1.00 | 1.31 | 2.38 |
| PFP&C18 | 1.00 | 1.47 | 2.64 |
| C18 | 0.39 | 1.60 | 1.46 |
Stability test
Conditions for durability testing

Conditions for measuring theoretical plates
- Column: PFP&C18 5 μm, 2.1x150 mm
- PFP 5 μm, 2.1x150 mm
- Mobil phase: Acetonitrile/water=70/30
- Acetonitrile/water=60/40
