Supelco® Ascentis® Express Biphenyl HPLC and UHPLC Columns
Chromatography Columns
Ascentis® Express 90 Å Biphenyl high-speed, high-performance liquid chromatography columns are based on a superficially porous Fused-Core® particle design.

The particle provides a thin porous shell of high-purity silica surrounding a solid silica core. 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 of 2 μm. The bonded, densely endcapped, dimethyl-biphenyl stationary phase provides a stable, reversed phase packing with enhanced pi-pi and mild steric interactions due to the twoMore Product Information
