Measuring Analyte Charge by Potentiostatic Coulometry

Controlled-potential coulometry measures analyte amount by carefully controlling electrode potential during electrolysis. It is also called potentiostatic coulometry. A potentiostat keeps the working electrode at a set potential in a three-electrode system.

Controlled-potential coulometry, also known as potentiostatic coulometry, uses a three-electrode system where the working electrode's potential is carefully controlled using a potentiostat.

Platinum working electrodes are used when positive potentials are required, while mercury pool electrodes are preferred for very negative potentials.<...
