Polarography is a subclass of voltammetry where the working electrode is a dropping mercury electrode (DME) or a static mercury drop electrode (SMDE), which are useful for their wide cathodic ranges and renewable surfaces. It was invented by Jaroslav Heyrovský, for which he won the Nobel prize in 1959. ==Theory of Operation== Polarography is a vo...

polarography

An electrochemical technique for identifying and estimating the concentration of reducible elements by means of the dual measurement of the current flowing through an electrochemical cell (which contains the test solution) and the electrical potential between the two electrodes as the potential is increased at a constant rate by an external voltage...

polarography

Type: Term Pronunciation: pō′lăr-og′ră-fē Definitions: 1. That branch of electrochemistry concerned with the variation in current flowing through a solution as the voltage is varied; this will vary with the ionic concentration of reducible substances so that polarography can be used in chemical analysis.
