External Generation of Oxidizing Agents or Reducing Agents
Shown here is one example of a device for the external generation of oxidizing agents and reducing agents for controlled-current coulometry. A solution containing the mediator flows into a small-volume electrochemical cell. The resulting oxidation products, which form at the … Continue reading

Controlled-Current Coulometry
A second approach to coulometry is to use a constant current in place of a constant potential, which produces the current–time profile shown here. Controlled-current coulometry has two advantages over controlled-potential coulometry. First, the analysis time is shorter because the … Continue reading
