VOLTAMMETRY

VOLTAMMETRY. A.) Comparison of Voltammetry to Other Electrochemical Methods 1.) Voltammetry: electrochemical method in which information about an analyte is obtained by measuring current (i) as a function of applied potential - only a small amount of sample (analyte) is used.

Potential Step

Potential Step. The working electrode is a microelectrode , and the solution volume is large enough that the passage of current does not alter the bulk concentrations of electroactive species. Such circumstances are known as small A/V conditions.
