ELECTROCHEMICAL SENSOR

摘要

The invention relates to electrochemical measurements in particular to electrochemical analysis of the constituents of a solution. The electrochemical sensor consists of a cup-shaped chamber at the bottom of which the following four electrodes are placed on a same plane: a measuring working electrode, an electrode for comparison, an auxiliary electrode and an electrode for sample preparation. The application of the electrode for sample preparation and the stirring of the solution reduce the threshold of detectability and increase the reproducibility of results.
