本文提出一种结构简单坚固准确度高的机械式方波极谱仪,讯号燥声比很高。最高灵敏度,可测出2×10-8M电极反应为可逆的离子。仪器中并有测量方波半周期i-t曲线的装置,可用以研究电极过程。

A simple, robust, and high precision mechanical square-wave polarograph is described which has a very high signal-to-noise ratio, and thus greatly reduced interference due to "capillary response".With this instrument reversibly-reduced ions such as Cd2+ and Pb2+ at concentrations down to about 2×10-8M can be detected.This instrument also includes a device with which the i-t curve in each half period of the square wave voltage can be obtained.It is a convenient tool for the investigation of the mechanism of electrode processes.
