Quick Summary

potential ramps
potential ramps Figure 3: The potential ramps applied to the indicator electrode during selected forms of polarography and the corresponding polarograms. E is the potential; I, the current; δI, the current difference; IAC, the AC current; t, the mercury electrode drop time; and m, the points at which measurements are made.

Pulse voltammetry is an electroanalytical technique used in chemical analysis. It involves applying a potential to an electrode immersed in a solution containing the analyte and monitoring the resulting current. In pulse voltammetry, a regularly increasing potential pulse is applied at periodic intervals. The current is measured during these pulses and plotted against the potential to create a voltammogram. This method, along with its variations like differential pulse voltammetry, is used for both qualitative and quantitative analysis of various substances. Electroanalytical methods, including voltammetry, rely on the analyte's ability to gain or lose electrons at the electrode surface.123
