Preferred Label : summit current;
Detailed label : summit current in polarography;
IUPAC definition : In ac polarography, differential pulse polarography, derivative polarography, square-wave
polarography, 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
applied potential ) 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 apex
current is recommended as being more specific.;
