Amperometric and Coulometric Sensors

Amperometric sensors are based on the electrochemical reduction of oxygen, and are governed by the diffusion of the electroactive species through a barrier - that is, holes or porous layers 81,82], The coulometric sensors are based on a similar concept, and were developed for closed-chamber systems. Although very few amperometric and coulometric sensors have been studied to date, some relevant examples are summarized in Chapter 13.

The development of electronics becomes a very promising tool for sophisticated devices, for instance, for amperometric and coulometric sensors. Analytical methods such as volta-...
