Ultisil PFP, Semi-Prep Cartridge: 5µm, 120Å, 10×10mm

Welch preparative guard column cartridges use the same packing as the preparative column, which can intercept some of the same polar substances in the sample and prevent them from contaminating and damaging the packing materials in the preparative column. 10×10mm cartridge holder: 00808-01116, 21.2×10mm cartridge holder: 00808-01106, 30×10mm cartridge holder: 00808-01117, 50×10mm cartridge holder: 00808-01110.

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.
