Abstract

A process is provided for the electrochemical analysis of compounds of solutions, such as can, e.g., be used in chemical analysis or for control measurements in industrial and environmental sectors. Identification or detection of individual substances takes place by the deposition thereof on electrodes and subsequent detection of the deposited substances. In the process, use is made of a plurality of electrodes. The substances to be identified from the solution are so simultaneously deposited on the electrodes that each electrode is coated with a different substance or substance mixture. Then, the deposited substances are simultaneously identified on the individual electrodes. Thus, the measuring time is significantly shortened and the risk of faulty measurements due to interactions between the substances to be identified on the electrodes is significantly reduced.
