Title:
OPTICAL SPECTRUM MULTIVARIABLE ANALYZER AND MULTIVARIABLE ANALYSIS METHOD
Document Type and Number:
Japanese Patent JP2022179047
Kind Code:
A
Abstract:
To solve the problem of prior art that when analyzing a substance whose components are unknown, it is not easy to appropriately determine a pure spectrum, which is an obstacle to improving the reliability of an MCR method.SOLUTION: A multivariable analyzer 1 comprises: a multivariable curve decomposition unit 10 for separating provisional f pieces of provisional pure spectra (k1, k2 through kf) from m measured spectra (a1, a2 through am) and calculating the provisional concentration value (c) of the provisional pure spectra and each of the provisional pure spectra; a provisional image generation unit 22 for generating, for each provisional pure spectrum (k), the distribution information of provisional concentration values (c) with respect to the positions of m measurement points, on the basis of the calculated provisional concentration values (c); and a grouping unit 24 for grouping the provisional f pieces of provisional concentration distribution image on the basis of the coincidence degree of images and determining the number (f') of multiple components of the sample on the basis of the number of groups.SELECTED DRAWING: Figure 1
