Abstract
The invention is for measuring the concentration of a target component accurately, and is an analysis device that analyzes a target component included in a sample. The analysis device includes a light source that outputs the reference light toward the sample, a photodetector that detects an intensity of sample light that is the reference light having transmitted through the sample, a parameter determining unit that determines a parameter representing a change in a light absorption spectrum of the target component or a change in a light absorption spectrum of an interference component, the change being caused by a coexisting component included in the sample or by a wavelength shift of the reference light, and a concentration calculating unit that calculates a corrected concentration of the target component, by using the parameter representing the change in the light absorption spectrum.
