Ascentis系列液相色谱柱是目前sigma-aldrich公司旗下分析品牌Supelco的主打色谱柱品牌。具有如下优点：
—B型超高纯球形硅胶基质，具有良好的表面惰性、重现性和稳定性
— 现代键合工艺优化了键合相的表面覆盖率、最大化稳定性，同时也减小了键合相的流失、降低了不必要的次级保留效应
—多种化学键合相和硅胶柱提供了较宽的选择性
—具有增强极性化合物保留的化学键合相，如Ascentis RP-Amide（反相酰胺）柱
—极低的柱流失、基线平稳，适用于LC-MS
—多种色谱柱型号满足从分析到制备的规模
—高表面积硅胶拥有高的色谱柱载样量，非常有利于制备色谱
此外为满足广大用户应用的需求，Sigma-Aldrich公司推出《Ascentis液相色谱柱应用谱图集》。该应用谱图集聚焦药物、食品、农残和环境等行业，包含大量热门检测应用，提供了两百多个液相应用图谱，并提供中文名、英文名、CAS号索引。欢迎致电010-82796427或email至feimeisi@vip.163.com 索取该应用谱图集资料。

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..
