Ohmic Drop Compensation In Electrochemical Measurement, Jia-Qi Chen, Xu-Xu Ye, Ling-Wen Liao, Zhen Wei, Mian-Le Xu, Yan-Xia Chen

Journal of Electrochemistry

The solution resistance (R_u) between the working electrode (WE) and the reference electrode (RE) may lead to significant Ohmic drop (iR_u) and deviation of actually applied potential at the WE to the desired ones in electrochemical measurement. In the case of high current or large R_u, iR_u compensation is imperative. Errors associated with insufficient compensation of theiR_u drop may significantly affect the accuracy of data measured by conventional electrochemical methods, which may consequently result in wrong judgment and conclusions. In this article, we discuss important factors which may affect …
