A Digitalized Polarograph and Its Application to the Analysis of Fluctuating i-t Curves

Abstract
The construction of a polarographic instrument based on a digital computer is outlined, and typical examples of its application are presented. The instrument is composed of an on-line system in which a digital computer with analog-to-digital and digital-to-analog converters is connected to a polarographic circuit. This instrument can be started at any moment of life of a mercury drop, and the polarographic current is digitalized. By the use of this instrument, the autocorrelation functions of noiselike fluctuations observed in the i-t curves of the maximum wave and the minimum wave were obtained.
