AbstractFor a long time the attention of many analytical chemists in various countries has been attracted by the problem of studying the composition of small amounts of matter.The development of this interesting and practically important field of analytical chemistry is much indebted to the investigations, carried out by a number of outstanding chemists of our time.Emich, Pregl, Hechtin Austria, and the Russian analystsKorenman, Komarovsky, Tananaev, Malyarovand others, might be mentioned in this connection. The development of microchemistry owes much tovan Nieuwenburg, who, as long ago as 1937, wrote, that microanalysis, as he was firmly convinced, might be and would be the chemical analysis of the futureC. J. van Nieuwenburg, Mikrochemie21, 184 (1937).. A great propagandist of microchemistryIdem., Bull. soc. chim. France No. 11–12, c.63 (1953).Idem., Chim. Anal.38, (12), 423 (1956).Idem., Analyst81, 450 (1956).he considered the future development of micromethods and mentioned ultramicroanalysis.In this paper a short description of some of our investigations on electrochemical methods of ultramicroanalysis is given.
