Verfahren zur elektrochemischen Analyse

The invention relates to a process for the electrochemmical analysis of solutions, as used, for example, in chemical analysis or for checking purposes in industry and environmental engineering. Individual substances are detected by depositing them on electrodes followed by detection of the deposited substances. Whereas, in known processes, all the substances to be detected are deposited on an electrode and detected one after the other, in the process according to the invention, numerous electrodes are used. The substances to be detected are deposited from the solution simultaneously onto these electrodes in such a way that every electrode receives the deposit of a different substance or a different substance mixture. Then the deposited substances are detected simultaneously on each of the electrodes. This drastically shortens the measuring time and the risk of incorrect measurements is greatly reduced due to interactions between the substances to be detected on the electrodes.
