Electrochemical impedance spectroscopy (EIS) – a powerful electrochemical technique

This white paper on electrochemical impedance spectroscopy (EIS) covers the basics of this technique as well as important points that need to be considered in order to generate meaningful data. Typical possible sources of error are mentioned as well as helpful tips for good measurements. In particular, the "sub-harmonic sampling" technique is discussed, which can be used to further improve the accuracy of EIS measurements.
