Ultisil® PFP, 3µm, 4.0x125mm, HPLC Column

The Ultisil PFP HPLC column 125x4.0mm, 3µm, bears pentafluorophenyl groups on ultra-pure silica. Ultisil PFP exploits hydrophobic, dipole, π-π and shape interactions and is suitable for halogenated analytes, polar aromatics, positional isomers, pharmaceutical active substances and metabolites.

Features and Benefits

• Wide selection of phases
• Ultra-pure, spherical, and fully porous silica
• Controlled phases for reproducible peak shapes
• Analytical, UHPLC, semipreparative, and preparative formats
• Application-specific and general-purpose columns

Additional Notes

According to the manufacturer, “Ultisil” and “Ultimate” refer to the same packing material under different regional naming conventions. The choice of modification depends on polarity, charge, molecular size, aromaticity, and the desired retention mechanism. Coated chiral selectors may only be used with approved eluents; ion-exchange and mixed-mode phases require joint optimization of pH, ionic strength, and organic content.
