Abstract: Based on an HT voltage value of each data point applied to a light detector and a plurality of reference spectra measured, in measurement of a reference substance performed for a plurality of times, a weighting function deriver of a spectrum measuring device derives a relation between the HT voltage value (HTi) and a degree of dispersion ?i of a plurality of spectral values as a weighting function (?=f(HT)). Moreover, a numerical evaluator of the spectrum measuring device is configured to calculate a degree of individual coincidence between a sample spectrum and the reference spectrum, acquire the degree of dispersion ?i by applying the HT voltage value at measuring the sample spectrum to the weighting function as a weighting value, and evaluate the difference between the reference spectrum and the sample spectrum based on the degree of individual coincidence to which the weighting value is applied.

Abstract: The present invention relates to improvement in accuracy in a device and a method for determining whether a spectrum of a target sample coincide with a standard spectrum or not. A spectrum determination device 10 determines whether a sample spectrum coincides with a reference spectrum or not by the reference spectrum obtained from a spectrum group. The spectrum determination device 10 comprises a storage unit 26 for storing the reference spectrum, and a determination unit 28 for comparing the reference spectrum and the sample spectrum to determine a sample 20 from the comparison result. The reference spectrum is set with a differing weighting for each point. The determination unit 28 calculates an individual coincidence with the sample spectrum for each point of the reference spectrum, and calculates a coincidence of the sample spectrum with the reference spectrum by the individual coincidence and the differing weighting to determine the sample 20.
