Description of PFP HPLC Column
A PFP(pentafluorophenyl) HPLC column was obtained by substituting a fluorine atom for five hydrogen atoms on a phenyl column. In addition to high selectivity to fluorine-containing and halogen-containing compounds, the fluorine-containing stationary phase can also be used as a general reversed-phase stationary phase for the separation of halogen-free or chlorine-free halogen compounds to provide a CH alkyl group. The selectivity of the stationary phase is different. Widely used in RP column HPLC like biopharmaceuticals, hot products, and environmental analysis.
The fluorinated stationary phase, H on the benzene ring is substituted by F and has stronger ion exchange and polarity separation characteristics than in the alkyl stationary phase. Separation can be achieved: separation of phenols, aromatics and amines, steroids, and natural products of paclitaxel.
- Separation of natural products for fluorochemicals and paclitaxel
- PFP also has high selectivity for aromatic compounds.
- Can retain basic compounds, lower than the hydrophobicity of C18
- Can be in reverse phase, HILIC
- Can operate in 100% pure water mode
- Stable, low loss, suitable for LC-MS, LC-UV
