AC Impedance Characterization of Highly Resistive Media Using Four-Electrode Electrochemical Cells

Abstract: Electrochemical impedance spectroscopy (EIS) was employed for characterization studies of highly resistive non-aqueous media using four-electrode cells with solid state reference electrodes. The influence of internal resistance of the impedance analyzer, the media's temperature and conductivity, shielding of the cables, and the electrochemical cell geometry and configuration on the impedance results were investigated.The most accurate EIS measurements can be made in the 2-electrode cells with active shields wh… Show more

“…Dielectric spectroscopy (DES) (also called electrical impedance spectroscopy, EIS) is an important technique to explore the polarization mechanism and relaxation behavior of dielectric materials, which could monitor the oxidative degradation process of lubricating oil arising from the polarity increase of oxidized products. Lvovich et al studied the influence of electrode electrochemical cells on the high-resistive lubricating oil, , applied the DES technique to monitor the oxidative degradation and condition of lubricating oil, and designed and fabricated electrical chemical sensors to detect the TAN based on the their EIS characteristics. ,, Perez et al designed and applied cylindrical capacitors to monitor the condition of the lubricating oil . Guan et al noted that DES could quantitatively and accurately determine the TAN and IC during simulated oxidative degradation .…”
