At the start of the 19th century much of the development of electrochemistry revolved around the study of chemical transformations by electrolysis, which then led to the quantitative analysis by extensive electrolysis. The early work of Faraday, Fick, Nernst and others laid the foundations for the development of polarography and voltammetry in the early 20th century, by which time Potentiometrie and amperometric techniques, with their improved specificity over conductance techniques, were being more widely developed. Around this time the analytical chemist was also becoming more interested in the determination of trace substances in samples and in 1929 Heyrovsky and Berezicky demonstrated the first amperometric titration using a dropping mercury electrode. Since then, steady progress has led to a wide assortment of electrochemical techniques and instruments being developed for use in an ever-widening range of applications.
