摘要 |
In order to suppress base line drift due to change in a light source and to start analysis with a short waiting time so as to improve quantitative accuracy of analysis, a detected signal in a measurement wavelength and a detected signal in a reference wavelength are measured at each of arbitrary light intensity points by varying light intensity of a light source, and the corresponding relationship between the wavelengths is stored. An incident light intensity of the measurement wavelength is estimated from a detected signal in the reference wavelength based on the stored data.
