With the purpose of fast characterization of electrode reactions, a dynamic electrochemical impedance spectrum (dEIS) measurement system has been assembled which permits the continuous collection of audio-frequency impedance spectra while performing cyclic voltammetry measurements with the usual scan rates of up to 200 mV/s. The performance of this system was tested by analyzing the CV curves and impedance spectra taken simultaneously in ferro-/ferricyanide containing aqueous solutions yielding an experimental demonstration of the connection of the semi-integrated reversible voltammograms and the Warburg coefficients.

CV和可逆氧化还原系统的阻抗谱的连接，用于验证动态电化学阻抗谱测量系统

为了快速表征电极反应，已组装了动态电化学阻抗谱（dEIS）测量系统，该系统可连续采集音频阻抗谱，同时以高达200 mV / V的常规扫描速率执行循环伏安法测量s。通过分析在含铁氰化铁溶液中同时获得的CV曲线和阻抗谱，测试了该系统的性能，得出了半积分可逆伏安图和Warburg系数之间联系的实验证明。
