Utility
Measurement of electric signals to detect presence or flow of electroactive species in solution
22 Jun 20
An electrochemical sensor may measure the flow of ions and/or electrochemical species in a solution passing the sensor because the electroactive species will continually come into contact with the electrode and an electric signal will be generated by the combination of diffusion and convection bringing the electroactive species to the electrode.
