采用自制的高效毛细管电泳扫描伏安电化学检测装置，在磷酸盐缓冲溶液中进行了肾上腺素、异丙嗪和氯丙嗪的分离检测，在优化的条件下获得了较好的检测重现性和低的检出限。结果表明，采用扫描伏安电化学方法不但能够减少电极的污染，而且可以在电泳过程中获得被测物质的伏安特性及检测体系的动态伏安图，更有利于被测物质的识别 The self-made high performance capillary electrophoresis scanning voltammetric electrochemical detection device, in phosphate buffer solution for the determination of epinephrine, promethazine and chlorpromazine separation and detection, under optimized conditions to obtain a better detection reproducibility And low detection limit. The results show that the scanning voltammetric electrochemical method can not only reduce the electrode contamination, but also obtain the volt-ampere characteristic of the tested substance and the dynamic voltammogram of the testing system during electrophoresis, which is more conducive to the identification of the tested substance
