PEIS or GEIS? That is the question.

Electrochemical Impedance Spectroscopy (EIS) measurements are generally performed under potentio control (PEIS) rather than under galvano control (GEIS). In most cases, the potentio and galvano modes are equivalent and give the same results, except in some cases when galvano mode is recommended, for example, when the system changes during the measurement…
