DISCRIMINATION METHOD USING NEAR-INFRARED SPECTRUM

摘要

PROBLEM TO BE SOLVED: To provide a method of drawing a discrimination line drawable even in the case of no abnormal article, and enabling everybody to discriminate between an abnormal article and a normal article simply and accurately, and a discrimination method using the discrimination line.;SOLUTION: The method of drawing the discrimination line for discriminating an abnormal article includes [1] (a) a process for measuring a near-infrared spectrum of the normal article, (b) a process for calculating a standard spectrum and a standard deviation (σ) based on the near-infrared spectrum acquired in the process (a), and (c) a process for drawing the discrimination line based on the standard deviation (σ) acquired in the process (b). This discrimination method of the abnormal article includes (d) a process for measuring the near-infrared spectrum of a discrimination object sample, and (e) a process for comparing the absolute value of a deviation of the near-infrared spectrum acquired in the process (d) to the standard spectrum acquired in the process (b) of [1] with the discrimination line drawn by the method described in [1].;COPYRIGHT: (C)2006,JPO&NCIPI
