Polarography is an electrochemical method enabling the analysis and quantitative measurement of very small quantities of a number of substances, among others the oxygen. This method has been elaborated by Czech physical chemist Jaroslav Heyrovský. He introduced the dropping mercury electrode for measuring current and after having connected a sensitive galvanometer he began to measure and record continuously even minute quantities of oxygen in fluids, among other media in blood. He called the method polarography and developed it for practical use in laboratories and upheld it worldwide. For this invention Heyrovsky was awarded the Nobel Prize for chemistry in 1959.
