Descriptor polarografía
Scope note: Técnica electroquímica empleada para medir la corriente que fluye en una solución en función del voltaje aplicado. La onda polarográfica observada, resultante de la respuesta electroquímica, depende del modo en que es aplicado el voltaje (barrido lineal o impulso diferencial) y el tipo de electrodo utilizado. Generalmente se usa un electrodo indicador de mercurio.

Scope note: An electrochemical technique for measuring the current that flows in solution as a function of an applied voltage. The observed polarographic wave, resulting from the electrochemical response, depends on the way voltage is applied (linear sweep or differential pulse) and the type of electrode used. Usually a mercury drop electrode is used.
