1. An analyzing method comprising:

  • a relation determination step of determining a relationship between variations of reflectivity and variations of wavelength with respect to a reference board whose reflectivity varies continuously as the wavelength of light irradiated onto the reference board varies, the variations of the wavelength of irradiated light being caused by environmental temperature changes that also cause fluctuations of reflectivity;

    a first detection step of irradiating light onto a reaction system to detect an amount of light reflected from the reaction system as a first detection result, the reaction system including a sample liquid and a reagent;

    a second detection step of irradiating light onto the reference board to detect an amount of light reflected from the reference board as a second detection result; and

    a calculation step of calculating the wavelength of irradiated light based on the second detection result and the relationship between variations of reflectivity and variations of wavelength with respect to the reference board while also calculating a concentration of a specific component in the sample liquid based on the first detection result and the calculated wavelength of irradiated light.
