一般描述

Ascentis® Express 2μm C8 UHPLC columns are based on a 90 Å 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 0.4-micron thick porous shell and the small overall particle size of 2-microns. The densely bonded, extensively endcapped dimethyloctyl stationary phase of Ascentis Express 2μm 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.
