Polarography vs. Voltammetry

Polarographynoun

(chemistry) An electrochemical technique for the analysis of redox reactions.

Polarographynoun

an electrochemical method of chemical analysis

Polarography

Polarography is a type 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 in 1922 by Czech chemist Jaroslav Heyrovský, for which he won the Nobel prize in 1959.

Voltammetrynoun

Any of several electrochemical analytical technique in which a current is measured as a voltage is varied.

Voltammetry

Voltammetry is a category of electroanalytical methods used in analytical chemistry and various industrial processes. In voltammetry, information about an analyte is obtained by measuring the current as the potential is varied.
