Impedance was measured using four-lead connections to each EC, which is mandatory given the extremely low series-resistance of such devices. And for this same reason, impedance measurements were made using a special instrument, a Gamry Reference 3000 Potentiostat/Galvanostat/ZRA operated using its “Hybrid EIS”

Tips from Technical Support
How and Why Gamry Instruments’ software integrates a CV scan via a trapezoidal numerical method, and always integrates current with respect to time. This means that when a CV is displayed as voltage versus current, “behind the scenes” the software still pulls current and time columns from the data file. Hence the units that are generated from integration are always coulombs, regardless of the units shown on the plot on your screen.
Integrating CVs gives you the amount of charge passed during a scan. This could be the amount of charge for a Faradaic reaction such as a redox active film or non-Faradaic reaction such as double-layer capacitance. This technical note gives a quick explanation on how to integrate in Echem Analyst.
