介绍了三种用于毛细管电泳/电化学检测器的接口的制作方法,对三种结口的性能作了比较.用自制高效毛细管电泳/电化学检测系统对Cu~(2+)所作的区带电泳表明,Nafin溶液制备的C型Nafion密封膜式接口性能最好.尽管三种接口均允许对分离毛细管施加电压,且可有效地隔离两个电化学系统的干扰,但C型接口不会给系统引入附加体积,电阻小,强度高,制作工艺简单. Three kinds of interface methods for capillary electrophoresis / electrochemical detector are introduced, and the performance of three kinds of junctions is compared.Using self-made high performance capillary electrophoresis / electrochemical detection system for Cu ~ (2+) Electrophoresis showed that Nafin membrane type C was the best prepared with Nafin solution.While all three interfaces allowed the voltage to be applied to the separation capillary and effectively interfered with the two electrochemical systems, the C-type interface did not Introduced to the system additional volume, low resistance, high strength, the production process is simple.
