Electrochemical Components Electrode surfaces
Boron-Doped Diamond Electrodes
Conductive diamond working surfaces for your electrochemical reactions.
Good to know
- Electrodes may be diamond bodies or diamond coatings on a support.
- Doping, coating thickness and substrate influence electrical behaviour.
- Exposed area and the back contact are separate parts of the electrode design.
