Cathode Ray Oscillography in A.C. Polarography and Tensammetry

Abstract

Applications of the cathode ray oscilloscope in a.c. polarography and tensammetry are described. The instrument is used to enable observation of the waveform of the alternating current and of the relationship between alternating current and time during the growth of a mercury drop. Some typical results are presented and it is shown that the method can provide useful information about electrode processes.
