stationary phase (CSP) was prepared by chemically bonding carboxymethyl-β-cyclodextrin (CM-β-CD) onto 3-aminopropyl silica gel through amidation reaction in water solution and was characterized by Fourier transform infrared spectroscopy (FT-IR), element analysis (EA) and thermal gravimetry analysis (TGA). The chromatographic performance was evaluated with 24 racemates under reversed-phase conditions
摘要通过水溶液中的酰胺化反应,将羧甲基-β-环糊精(CM-β-CD)化学键合到3-氨基丙基硅胶上,制备了手性固定相(CSP),并通过傅里叶变换红外光谱(FT-IR)对其进行了表征。 ,元素分析(EA)和热重分析(TGA)。在反相条件下用24个外消旋体评估了色谱性能。讨论了盐,有机改性剂,流动相pH和分析物结构的影响。与天然β-CD结合柱CYCLOBOND I 2000相比,CM-β-CDCSP表现出增强的对映体分离。
