一般描述
Astec CHIROBIOTIC® CSP(手性固定相)通过多种分子相互作用与可电离的极性和中性分析物相互作用。该属性使其具有广泛的通用性,从而使其可用于各种流动相。另一个特点存在离子相互作用,使它们可用于反相和极性离子模式进行敏感的 LC-MS 操作。CHIROBIOTIC® V 是基于结合万古霉素,万古霉素包含 18 个手性中心,周围有 3 个空腔或口袋。这些空腔被 5 个芳香环包围。氢受体和供体位点非常靠近环结构。CHIROBIOTIC® V 与糖蛋白相的选择性相似,不同之处在于它具有较高的样品容量,并且在 0-100% 的有机改性剂中稳定。
中性分子、酰胺、酸、酯和胺对这些基于万古霉素的CSP具有相当大的对映选择性。在极性离子模式下,在CHIROBIOTIC® V上可分离多种仲胺和叔胺。CHIROBIOTIC® V已被证明具有许多蛋白质固定相的分离特性,但又具有优异的稳定性和更高的样品容量。部分尚无采用其他手性固定相分离报道的手性分析物也已在其上得到分离。CHIROBIOTIC® V和V2的成键化学特性不同,载体颗粒的孔径不同,因而各自具有不同的灵敏度和制备能力。
- 键合相:万古霉素
- 工作pH范围: 3.5 - 7.0
- 粒径:5、10或16 μm

应用
Chirobiotic V HPLC 色谱柱可用于分离人血浆中西酞普兰的对映异构体及其两种 N-去甲基化代谢物和内标物阿普洛尔。
