とする二波長分光光度計。 Measure the absorbance at the main wavelength in the main absorption band of the solution sample and at the subwavelength where the degree of absorption is low, and use the difference or ratio of the absorbance at both wavelengths to reduce the influence of scattering etc. due to the sample and calculate the concentration. In the dual-wavelength spectrophotometer to be measured, first measure the absorbance at the dominant wavelength, then insert a reflective prism into the optical path of the spectrometer while keeping the dispersion of the spectrometer fixed.
A two-wavelength spectrophotometer characterized by measuring absorbance at a sub-wavelength by changing the wavelength of light emitted from an output slit of a spectrometer.
