基本信息
| General description【一般描述】 | Ascentis® Express 90 Å Biphenyl is a high-speed, high-performance liquid chromatography column 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 0.6 μm thick porous shell and the small overall particle size of 5 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 two sequential phenyl groups bonded to the base silica. The 90 Å Biphenyl can be used for basic, acidic, or neutral compounds with alternate selectivity from C18 and is especially useful for separating peaks that elute early on C18 and other phenyl phases. |
