摘要
在射壁式检测器的基规上，设计了一种用于毛细管电泳-电化学检测装置的检测池，巧妙地利用因表面张力现象而留驻波滴曲面的放大作用，直接调整毛细管与电极之间的相对位置，无需显微镜-微调节器装置，具有空间体积小，操作更简便的优点。
With end-column electrochemical detection in capillary electrophoresis (CE), precise positioning and stabilization of the working electrode are very important. In this paper I an electrochemical cell designed for end-colunm wall-jet amperometric detection in capillary zone electrophoresis is reported. In this cell, a curved surface was formed because of the surface tension and used as the amplifier. With this cell, alignment of the working electrode with the capillary outlet could be achieved precisely and easily without the help of a microscope and a micropositioner. Being compared with eletrochemical cell of other groups , this cell is simple and can be used more conveniently. Application of this electrochemical cell for electrophoretic separation of phenols is demonstrated. High resolution and low detection limits were obtained with this assembly.
