PFP Column
PFP Column The Zodiac PFP column is a high-performance chromatography solution designed for superior selectivity and retention. As a pentafluorophenyl (PFP) phase with a propyl spacer, this bonded phase delivers reversed-phase separations that stand apart from conventional C18 silica surfaces . The presence of highly electronegative fluorine atoms on the periphery of the phenyl ring ligand allows for unique aromatic selectivity , making it an excellent choice for challenging separations. PFP Column Exceptional Interaction Types for Enhanced Retention The Zodiac PFP column exhibits multiple interaction mechanisms that contribute to its high performance, including: Dispersive interactions : Effective for nonpolar compounds Dipole-dipole interactions : Enhancing selectivity for polar analytes Pi-pi interactions : Ideal for aromatic compounds Charge-transfer interactions : Providing superior retention for halogenated species These ...
