Abstract: A spectroscopic analyzer includes a first measurement section which measures a spectrum of near-infrared region by irradiating a sample with near-infrared light, a second measurement section which measures a spectrum of infrared region by irradiating the sample with infrared light, and an analysis section which analyzes characteristics of the sample using the spectra measured by the first and second measurement sections. The analysis section includes a first calculation module which acquires a integrated spectrum by combining the spectrum of near-infrared region and the spectrum of infrared region, a second calculation module which calculates a difference spectrum of a reference spectrum measured in advance and the integrated spectrum, and a third calculation module which calculates correlation between the spectrum of near-infrared region and the spectrum of infrared region by performing a two-dimensional correlation operation using the difference spectrum.
