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
The Phenyl-Hexyl phase has unique selectivity arising from solute interaction with the aromatic ring and its delocalized electrons. It is complementary (orthogonal) to both C18 and RP-Amide phases because of this unique aromaticity. The Phenyl-Hexyl phase also tend to exhibit good shape selectivity, which may originate from solute multipoint interaction with the planar ring system. More retention and selectivity will often be observed for solutes with aromatic electron-withdrawing groups (fluorine, nitro, etc.) or with a delocalized heterocyclic ring system such as the benzodiazepine compounds.
