PROBLEM TO BE SOLVED: To reduce errors in density measurement of components in particle dispersion liquid due to influence of particle density.SOLUTION: The absorption spectrometry apparatus calculates the density of a predetermined component liquid prepared by adding a particle dispersion liquid dispersed with particles in a liquid using an optical absorption spectrum which is obtained by applying a light beam to the particle dispersion, a prepared optical absorption spectrum and an analytical curve representing a relationship between the predetermined component and the density. The analytical curve is created on the basis of plural optical absorption spectrums which are measured on the predetermined components of plural densities different from each other.SELECTED DRAWING: Figure 2 |
