CONCENTRATION MEASUREMENT APPARATUS USING CYCLIC VOLTAMMETRY

摘要

The present invention relates to a concentration measurement apparatus using cyclic voltammetry. The concentration measurement apparatus measures the concentration of a material by using a current that is generated according to a cyclic electric potential applied from an electrode sensor unit by cyclic voltammetry, and may comprise: a storage unit for storing a reference electric potential, a scan range, a first reference concentration, a second reference concentration, and a first reference current and a second reference current, each of which is measured when the concentration of the material is the first reference concentration or the second reference concentration; a data acquisition unit for acquiring, from the electrode sensor unit, current data measured in a scan range centered at the reference electric potential after waiting for a predetermined cycle; and a concentration calculation unit for calculating the average current of a predetermined number of pieces of lower current data among the acquired current data, and calculating the concentration of the material, using the calculated average current, the first reference concentration, the second reference concentration, the first reference current, and the second reference current.
