Ultisil PF-Phenyl

Ultisil Fluorinated Phase has high selectivity and increased retention toward closely related compounds, not just for aromatic fluorinated compounds, but also for other nonaromatic halogenated compounds. It could be used as usual reverse phase and provide an alternative and complementary separation for many analytes performed on C8 or C18 columns. Fluorinated phase has better separation for the ion exchange and polar compounds than alkyl phase. Fluorinated phases can provide different elution orders, leading to enhance selectivity for difficult-to-separate compounds.

Ultisil PF-Phenyl is a phase primarily used in the separation of molecules bearing fluorine atoms, but may also be in the separation of non-fl  uorous compounds such as Taxol and its derivatives. Because of its phenyl ring, it has a higher selectivity for aromatics containing molecules compared to the other alkyl-fl  uorinated phase. Ultisil PF-Phenyl can separate nitro-benzene isomers (para vs. ortho), which cannot be separated by traditional phenyl phase.
