A new method is introduced for the detection of dissolved analytes which can be deposited at noble metal electrodes. It is based on the measurement of surface resistance‐potential curves at thin‐film electrodes and has been named voltohmmetry. The measuring principle, fundamental prerequisites and the necessary experimental set‐up are described. As an example the deposition and dissolution of lead has been studied by cyclic voltohmmetric experiments at specifically prepared thin‐film gold electrodes. The present possibilities and limitations of surface resistance‐potential measurements for electroanalysis are discussed.
