Electrochemical measurement principle based on measurement of current at a controlled applied potential.
Notes:
The current is usually faradaic and the applied potential is usually constant.
Amperometry can be distinguished from voltammetry by the parameter being controlled (electrode potential E
) and the parameter being measured (electrode current I
which is usually a function of time - see chronoamperometry).
In a non-stirred solution, a diffusion-limited current is usually measured, which is proportional to the concentration of an electroactive analyte.
The integral of current with time is the electric charge, which may be related to the amount of substance reacted by Faraday’s laws of electrolysis.
