Sunbridge PFP-R
Ideal For Both Short- And Long-Chain PFAS Analysis
The SunBridge PFP-R (3 µm) column introduces enhanced selectivity for fluorinated compounds (including both short- and long-chain PFAS), aromatic isomers, and polar analytes, offering unique retention characteristics that complement traditional C18 phases.
- Column focusing — peak shape maintained
- Temperature screening — impurity separation
- LOD ≤ 0.05 μg/kg for all target PFAS
- Clear separation ― Branched and linear PFAS
The Redesigned PFP for Reversed-phase
PFP-R: Redesigned PFP For Reversed Phase Chromatography
Features of the PFP-R Stationary Phase
- Dipole–dipole interactions based on the strong electron-withdrawing
- property of fluorine
- π/π donor–acceptor interactions (strong recognition of aromatic rings)
- Tuned to provide moderate (rather than strong) retention for cations
- PFP designed with emphasis on stability as a reversed-phase
stationary phase - Note: The so-called “HILIC-like behavior” often attributed to PFP
columns (see figure below) does not occur.
