Abstract

See full text

The present invention intends to reduce a measurement error in the concentration of a component due to the effect of the grain concentration of grain dispersion liquid. Also, the present invention is one that calculates the concentration of a predetermined component added into grain dispersion liquid in which grains are dispersed in liquid, with use of a light absorption spectrum obtained by irradiating the grain dispersion liquid with light and a preliminarily prepared calibration curve representing the relationship between a light absorption spectrum and the concentration of the predetermined component. Further, the calibration curve is prepared on the basis of multiple light absorption spectra obtained by measuring light absorption spectra of multiple grain dispersion liquids having mutually different grain concentrations for each of mutually different multiple concentrations of the predetermined component.
