The invention relates to measurement engineering. Said invention makes it possible to increase the speed and accuracy of the measurement of a volt-ampere characteristic of a liquid-electrode surface interface within an extended range of working electrode potential values, wherein the accuracy of the volt-ampere characteristic measurement makes it possible to identify the individual sample components and the entire sample by means of image recognition methods. The inventive electrochemical analysis method consists in determining the volt-ampere characteristic of a cell by means of charge/dishrag cycles which are carried out by a specified current within the range of potential values on the working electrode, including the potential values of probable electrode reactions of the components, in dividing the potential range into intervals, in measuring the time for measuring a potential within the limits of said intervals during charging and discharging and in judging the concentration variation of a target component in the solution according to data related to the current and the charge and discharge length within each cycle interval. |
