Abstract
To check an influence to an absorbance due to a temporal variation of measuring light in an analyzing apparatus, the analyzing apparatus includes a reference gas filling space, a spectrum generating portion, and a spectrum comparing portion. The reference gas filling space is formed on an optical path of measuring light and is filled with a reference gas different from a measurement target gas at a first concentration. The spectrum generating portion generates measured spectrum data, associating a wavelength of a detection light beam as the measuring light after passing through the reference gas filling space with a relative intensity of the detection light beam. The spectrum comparing portion calculates a difference between the measured spectrum data and reference absorption spectrum data obtained by measuring in advance an absorption spectrum of the reference gas at the first concentration by a direct absorption method.
