Ascentis Express F5/液相色谱柱

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 F5 is a high-speed, high-performance liquid chromatography column based on the highly efficient Fused-Core® particle design. The bonded, endcapped, dimethylpentafluorophenyl-propylsilane stationary phase of Ascentis Express 5 μm F5 provides a stable, reversed-phase packing with electron-deficient phenyl rings due to the presence of electronegative fluorines. In addition to forming π-π and mildly steric interactions, F5 phases also retain compounds by polar interactions. As a result of having both polar and non-polar character, F5 phases can show dual-mode retention behavior, sometimes producing a “U-shaped” retention as a function of acetonitrile content of the mobile phase, with retention increasing at both low and high concentrations of ACN (reversed-phase and HILIC retention modes). Ascentis Express 5 μm F5 can be used for basic, acidic, or neutral compounds with alternate selectivity from C18.
