双指示电极示差伏安仪的研制

Double Working Electrodes Differential Voltammeter

双指示电极示差伏安仪是采用双工作电极的四电极测定体系。通过仪器内部的差值处理得到扣除背景的测量信号。仪器采用模拟式电路和数字电压指示系统,性能良好。 双指示电极。

A four electrodes differential voltammeter is described. The measurement signals sub-tracted of background can be obtained throug internal circuitry. Determinations can be per-formed in solutions without removing oxygen, Analogue circuits and digital voltage indi-cating system are used. The identity of two working electrods is guaranteed by physical, chemical and electrochemical methods.
