Ultisil PFP column is a phenyl column where fluorine atoms replace hydrogen atoms on the reversed-phase stationary phase carbon chain. It offers high selectivity for fluorinated and halogenated compounds. With strong geometric and steric shape selectivity, it effectively separates structurally similar compounds that are difficult to resolve with alkyl stationary phases.
