What equipment is required for voltammetry experiments?
First, a potentiostat is required for controlling the applied potential, and a current-to-voltage converter is required for measuring the current. These are both contained within the epsilon. A user interface is required to define the way the potential is applied – the potential waveform. There are a number of different potential waveforms, and these are referred to by characteristic names; for example, cyclic voltammetry, and differential pulse voltammetry. These different potential waveforms (or techniques) are discussed in more detail in the appropriate section. The epsilon must be connected to the electrochemical cell. This contains the three electrodes immersed in an electrolyte solution of the molecule.
