Sixty-five years ago Czech scientist Jaroslav Heyrovský won the Nobel Prize for Chemistry for his discovery and development of polarography, becoming the first Czech recipient of the prestigious award. The discovery, however, was made much earlier, on February 10, 1922.
This Saturday marks 102 years since the invention of polarography, a pioneering method analysing substances in solutions, developed by Czech chemist Jaroslav Heyrovský.
Polarography is based on the relationship between an increasing current passing through a solution and the increasing voltage used to produce the current, and is used to analyse the types of substances in solutions as well as their quantities.
