" /> summit current - CISMeF





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.;
