Investigations on if-E Curve in Cyclic Derivative Chronopotentiometry (Ⅴ)——A Microcomputer-based Data Acquisition System for if-E Curve Measurements

Introduction Quantitative analysis in cyclic derivative chronopotentiometry(CDC) is based on the measurement of the depth of incision on the (dE/dt)～E curve. A serious disadvantage of the method is that a large charging current obscures the measurement. To improve the sensitivity and the accuracy of CDC, a microcomputer-based data acquisi-
