Abstract

It is appropriate that a Congress, dedicated to the memory of Emich and Pregl, should make some reference to the development of the Microchemical Balance. The early microchemical balances (e. g. Warburg and Ihmori 1, Nernst 2, Steele and Grant 3), were designed for special purposes, and consequently had a limited load-capacity. Emich, and later, Pregl, persuaded the German balance manufacturer Kuhlmann to refine his assay balance, which was only suitable for a maximum load of 2 g. Under their stimulus, he produced an instrument with a 20 g capacity, and which was sufficiently accurate for microchemical analysis. Emich and Pregl appreciated the importance of instrumentation in the development of the new science and realised that the accuracy of analyses depends to a large extent on the performance of which the balance is capable.
