<p>PROBLEM TO BE SOLVED: To provide a new method, in which the information on specimen is obtained with higher accuracy in a nondestructive state, by using a near- infrared spectrum. SOLUTION: In the method which obtains the information on a specimen, (a) a process in which the specimen is irradiated with continuous wavelength light in the region of 400 to 2,500 nm or in a part of it and (b) a process, in which a peak in the obtained spectrum is decomposed to an element peak by a spectroscopic technique are contained. More specifically, the method discriminates a group to which an unknown specimen belongs, the method identifies the unknown specimen and monitors the aged deterioration of the specimen in real time. By this method, the information on the specimen can be obtained with higher accuracy, at a low cost, through the element peak of water molecules and in the nondestructive state by using a comparatively simple apparatus.</p> |
