摘要
The present invention responds flexibly to and corrects concentration changes that are caused by changes between the temperature when a correction calibration curve is created and the temperature when a test sample is measured, without having to correct the calibration curve. More specifically, a spectrophotometer measures concentrations of measurement target components contained in a test sample from an optical spectrum obtained by irradiating light onto the test sample, and includes a concentration calculation unit that calculates concentrations of the measurement target components from the optical spectrum using a calibration curve, and a concentration correction unit that, using a temperature correction formula corresponding to a wavelength region or a wavenumber region in which concentrations of the measurement target components are being determined, corrects concentration changes in the measurement target components that accompany temperature differences between a temperature when the calibration curve is created and a temperature when the concentrations are measured.
