Applied Waveform and Data-Acquisition

In a Sampled DC voltammetric experiment, a staircase voltage sweep is applied to the working electrode in an electrochemical cell. This staircase waveform is defined by the Step Size (mV) and the Sampling Period (seconds). The resulting waveform is seen in the figure below.The staircase generally uses 2 to 10 mV steps and a Sampling Period of 0.5 to 2 seconds. The effective scan rate is the Step Size divided by the Sampling Period.
