Collins Concise English Dictionary © HarperCollins Publishers:: polarography /ˌpəʊləˈrɒɡrəfɪ/ n - a technique for analysing and studying ions in solution by using an electrolytic cell with a very small cathode and obtaining a graph (polarogram) of the current against the potential to determine the concentration and nature of the ions.
