phase-transitioned BSA (PTB) film using the mild and fast fabrication process adhered to the capillary inner wall uniformly, and the fabricated PTB film-coated capillary column was applied to realize open tubular capillary electrochromatography (OT-CEC) enantioseparation. The enantioseparation ability of PTB film-coated capillary was evaluated with eight pairs of chiral analytes including drugs and neurotransmitters
在这项工作中,相变 BSA (PTB) 膜采用温和快速的制备工艺均匀粘附在毛细管内壁上,并将制备的 PTB 薄膜包覆毛细管柱应用于实现开管毛细管电色谱 (OT-CEC)对映分离。用八对手性分析物(包括药物和神经递质)评估了 PTB 薄膜包衣毛细管的对映分离能力,均获得了良好的分辨率和对称的峰形。对于连续 3 次运行,日内、日间和柱间重现性迁移时间的相对标准偏差 (RSD) 范围为 0.3%–3.5%、0.2%–4.9% 和 2.1% –7.7%,分别。此外,PTB 薄膜包衣毛细管柱连续运行 300 多次,分离效率高。所以,
