In 1920 was promoted to an assistant at the Department of Chemistry University of Prague, in 1922 - an extraordinary, and since 1926 - an ordinary professor of Chemical Physics of the University of. In 1922, investigating the electrolysis in electrochemical cell with a dropping mercury electrode, fixed relationship between the nature of substances and their potentials of oxidation and reduction. These works formed the basis of polarography method, widely used in analytical chemistry. In 1925 Heyrovskö+ (jointly with Japanese scientist M. Shikatoy) built polarography, the first automated device for analytical. In late 1920-1930-ies scientist strongly advocated his method: he gave lectures at the Sorbonne university in the United States, Soviet Union.
