Abstract

PURPOSE:To improve the accuracy of concn. measurement by selectively using two wavelengths based on the data of a multiwavelength spectrocolorimeter. CONSTITUTION:The light absorption characteristic 1 of coloring liquid, the light absorption characteristic 2 of a sample having absorption abnormality, and the light absorption characteristic 3 of a sample having no absorption abnormality are measured respectively by using a multiwavelength spectrocolorimeter. Based on the results of this multiwavelength measurement, such two wavelengths at which the influence by the factors for the absorption abnormality of the sample is the smallest are selected for the sample of abnormal absorption and the sample of normal absorption from the multiwavelengths, whereby the concn. of the unknown sample is measured. Namely, the quantitative analysis is accomplished by selecting the wavelengths lambdaa, lambdab in the case if doing the same by using the sample having absorption of abnormality, and by selecting the wavelengths lambdaa, lambdac in the case of the sample of normal absorption. In this way, the influence by the factors for the absorption abnormality is reduced and the accuracy of the concn. measurement is enhanced.
