多性能新极谱仪

A Multi-purpose Neopolarograph

多性能极谱仪,可记录电流的半积分(m)、半微分(e)、1.5次微分(e′)、2.5次微分(e″)对相应电压的曲线,即m～E、e～E、e′～E,e″～E曲线,也可记录循环伏安曲线。并在极低的支持电解质浓度下测定。

A multi-purpose neoplarograph system has been designed. The systemconsists of recording i-E, m-E, e-E, e′-E, e″-E and cycli voltammetric curves,where m and e are semioperators, the semiintegral and semidifferential, e′and e″are the 1.5th order and 2.5th order differential. The principles, construction andexperimental results are given. It shows that the sensitivity, resolution, reprodu-cibility and rapidity of the system are satisfactorily.
