<p><P>PROBLEM TO BE SOLVED: To provide a method for rapidly discriminating the content of the target detection component of a plastic material even if a very small amount of the target detection component is contained in the plastic material. <P>SOLUTION: The first infrared absorption spectrum, which is obtained by irradiating the plastic material with infrared rays having a continuous spectrum and measuring the intensity of totally reflected or transmitted infrared rays, is compared with the second infrared absorption spectrum obtained by irradiating the plastic material with infrared rays having the continuous spectrum while or after processing for applying a change to the wave number inherent to the target detection component in the plastic material is performed and measuring totally reflected or transmitted infrared rays to recognize the presence of the content of the target detection component. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
