Ohmic drop correction in electrochemical techniques. Multiple potential step chronoamperometry at the test bench

Ohmic drop correction is an important issue in the practice of cyclic and linear sweep voltammetry. While this problem has received satisfactory solutions over the last decades, a new approach, “multiple potential step chronoamperometry (MUSCA)” has been recently proposed. At the test bench, application of MUSCA is not only disappointing but the cure is clearly worse than the disease, opening the way to dangerous artefacts in the interpretation of experimental data.
