1. A solution quantitative analysis apparatus comprising:

  • an electrolytic cell for electrolyzing a solution containing a plurality of chemical species to be analyzed, the electrolytic cell including a working electrode, a counter electrode, and a reference electrode;

    means for producing a plurality of mutually different voltage-time waveform signals corresponding to a plurality of mutually different voltammetry modes equal in number to the plurality of chemical species to be analyzed;

    means for separately applying the plurality of voltage-time waveform signals to the working electrode, thereby performing the plurality of voltammetry modes, wherein each of the plurality of voltage-time waveform signals electrolyzes the solution, thereby producing a respective electrolysis current having one of a limiting current and a peak current depending on the corresponding voltammetry mode;

    means for measuring the one of a limiting current and a peak current of the electrolysis current produced by each of the plurality of voltage-time waveform signals; and

    means for calculating respective concentrations of the plurality of chemical species to be analyzed on the basis of the measured ones of a limiting current and a peak current.
