Non-traditional use of polarography and voltammetry

The paper discusses some rather non-traditional uses of polarography and vo ltammetry which are beyond common polarographic routine in analytical labor atories. Some potentials of polarography in the biological and biochemical fields are treated spanning from in vivo measurements to sensors for diagno stic purposes in medicine and toxicology. Examples are given of analyses in the solid and gas phases as well as the use in tribodiagnostics in determi nation of machine wear.
