General description
Ascentis Express 5 μm RP-Amide 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 μm thick porous shell and the highly uniform overall particle size of 5 μm. The one-step bonded, endcapped, amide-based, polar-embedded stationary phase of Ascentis Express 5 μm RP-Amide provides a stable, reversed-phase packing with decreased hydrophobic character. Ascentis Express RP-Amide can be used for basic, acidic, or neutral compounds with orthogonal selectivity from C18 or C8. The polar-embedded Ascentis Express 5 μm RP-Amide columns are compatible with 100% aqueous mobile phases without suffering from “phase collapse”.
