Single Frequency EIS is a technique in Gamry’s EIS application package. It is used to follow changes in electrochemical impedance versus time. The most common use is in impedance-based sensor development and in on-line sensor systems. It can also be used to follow degradation of batteries or coating systems. Unlike standard EIS, it does not provide a spectrum. Instead, Single Frequency EIS periodically measures electrochemical impedance at one frequency. The measurement is made with a constant DC potential applied to the cell.
