General description
Ascentis® Express 5 μm C8 is a high-speed, high-performance liquid chromatography column based on the highly efficient Fused-Core® particle design. The Fused-Core 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 0.6-micron thick porous shell and the highly uniform overall particle size of 5-microns. The densely bonded, extensively endcapped dimethyloctyl stationary phase of Ascentis Express 5 μm C8 provides a stable, reversed-phase packing that can be used for basic, acidic, or neutral compounds.

Saikosaponins are triterpene saponins derived from the roots of Bupleurum falcatum L. (Umbelliferae), which has been traditionally used to treat fever, inflammation, liver diseases, and nephritis. It is difficult to analyze saikosaponins using HPLC-UV due to the lack of chromophores.

When a C18 doesn′t give the desired separation, or your sample contains compounds that are known to be difficult to retain or resolve on a C18, consider changing to an Ascentis® Express C8 column.
