Kanak HPLC columns – PFP

Due to the highly electron deficient nature of the aromatic rings of Kanak PFP, the stationary phase will interact strongly with analytes containing polar aprotic and electron-rich aromatic moieties. This contrasts with the Kanak Phenyl Hexyl stationary phase.

Additionally, the electronegative fluorines of the pentafluorophenyl group will provide strong hydrogen bonding with analytes with protic moieties, such as hydroxyl groups and carboxylic acids. Furthermore, the delocalized charge over the fluorine-carbon bond will interact with analytes containing dipole moments. Thus, Kanak PFP will give different selectivity compared to Kanak Phenyl Hexyl. The polar nature of Kanak PFP ensures a fully wettable stationary phase, enabling Kanak PFP to analyze very polar compounds.
