描述了一种毛细管电泳微机化扫描伏安检测器,用微机通过D/A和A/D转换器控制扫描电压和采集电流信号,用12bit的D/A转换器和12bit的A/D转换器通过伏安仪分别与Ag/AgCl参比电极和工作电极相连,进行电位控制和数据采集.讨论了扫描电位的产生和数据采集的控制方法,并用本系统分离测定了对苯二酚和儿茶酚,结果令人满意
Describes a capillary electrophoresis scanning voltammetry computerized detector, the computer through the D / A and A / D converter to control the scanning voltage and current signal acquisition, with 12bit D / A converter and 12bit A / D converter By voltammetry with Ag / AgCl reference electrode and the working electrode connected to the potential control and data acquisition. The formation of scanning potential and the control method of data acquisition were discussed. The separation and determination of hydroquinone and catechol by this system were satisfactory
