Description

Direct coulometry at controlled potential in which the electric charge passed after the application of a potential step perturbation is measured as a function of time (Q-t curve). Chronocoulometry provides the same information that is provided by chronoamperometry, since it is based on the integration of the I-t curve. Nevertheless, chronocoulometry offers important experimental advantages, such as (i) the measured signal usually increases with time and hence the later parts of the transient can be detected more accurately, (ii) a better signal-to-noise ratio can be achieved, and (iii) other contributions to overall charge passed as a function of time can be discriminated from those due to the diffusion of electroactive substances.
