In ac @[email protected], differential pulse @[email protected], derivative @[email protected], square-wave @[email protected], and similar techniques, the maximum value of the component of the current that is associated with the presence of a substance B. Normally this component of the current is faradaic, and the maximum arises because the rate of variation (with @[email protected] ) of the rate of the charge-transfer process passes through a maximum. Similar maxima arise when this component is non-faradaic (and when B is surface-active rather than electroactive). In a case known to be of the latter type, the term @[email protected] is recommended as being more specific.
