Supelco® Ascentis® Express F5 (PFP) HPLC and UHPLC Columns
Chromatography Columns
Ascentis® Express F5 (PFP) high-speed, high-performance liquid chromatography columns are based on the highly efficient Fused-Core® particle design.

This particle design exhibits very high column efficiency due to the shallow diffusion paths in the 0,4 μm thick porous shell and the small overall particle size. The bonded, endcapped, dimethylpentafluorophenylpropyl stationary phase of Ascentis® Express F5 provides a stable, reversed phase packing with electron-deficient phenyl rings due to the presence of electronegative fluorines. In addition to forming pi-pi and mildly steric interactions, F5 phases also retain compounds by polar interactions.

Having a polar and non-polar character, F5 phases can show dual-mode retention behaviour, sometimes producing a 'U-shaped' retention as a function of acetonitrile content of the mobile phase, with retention increasing at both low and high concentrations of ACN (reversed-phase and HILIC retention modes). Ascentis® Express F5 can be used for basic, acidic or neutral compounds with alternate selectivity from C18.
