The focused protein zones were eluted to the entrance of MS by combining cathodic mobilization with gravity.

已聚焦好的蛋白质区带通过结合阴极移动和重力移动的方法从毛细管中流出而进入质谱仪。

Sitafloxacin epimers were separated by capillary zone electrophoresis using γ-cyclodextrin and D-phenylalanine as chiral selector.

以γ-环糊精和D-苯丙氨酸为手性选择剂，采用毛细管区带电泳成功地分离了新型抗菌素西他沙星差向异构体。

A baseline separation of Sitafloxacin epimers was achieved with a background electrolyte of 10 mmol/L KH2PO4-K2HPO4 (pH 4.5), 10 mmol/L CuSO4, 20 mmol/L γ-CD and 10 mmol/L D-Phe. The linear range for Sitafloxacin was 32-400 mg/L (0.996). The relative standard deviations of migration time and peak area were less than 1.9% and 3.8% respectively.

实验结果表明，添加剂的种类和浓度是影响西他沙星手性分离的重要因素，只有当D-苯丙氨酸、铜离子和γ-环糊精同时存在并达到一定浓度时，西他沙星差向异构体在毛细管电泳中才具有良好的分离效果。
