description PROBLEM TO BE SOLVED: To obtain a method and an apparatus in which a test substance is identified and in which the degradation state of the substance can be measured quantitatively and in a short time. SOLUTION: Near-infrared light or infrared reflected light which is reflected from the surface of the test substance is spectrally diffracted by a spectral apparatus 10. In a state such that the obtained spectral data on the test substance and the time-dependent degradation calibrated absorption spectrum group of various substances stored in advance in a database 21 are standardized by a standardization means 22, the time-dependent degradation calibrated absorption spectrum group is substance-retrieved by a retrieval means 23 on the basis of spectrum data on the test substance, and the substance is identified. In addition, by referring to the time-dependent degradation calibrated absorption spectrum group of the identified substance and that of a substance similar to the substance, the substance composition ratio, the degradation history time or the like of the test substance is calibrated and calculated by a calibration means 24. Its calculated result is outputted by an output means as a result in which the substance to be inspected is identified or the degradation state of the substance is converted into a numerical value.
