Automatic analysis method, a program for an automatic analyzer and an automatic analyzer

摘要

Automatic analysis method that can determine the number of components contained The sample more accurately and easily, provides an automatic analyzer and automatic analyzer program. Based on the degradation spectral data obtained by multivariate curve degradation using provisional component number k (MCR), to determine the component to determine the number of components contained in the sample based on the determination result. In this case, at least two decomposition spectra of each resolved spectrum data obtained with the provisional number of components k, multivariate curve degradation when it is determined that different components for all resolved spectrum data obtained by the multivariate curve degradation to the boundary value between the provisional number of components k in the case of the data it is determined that the same components are obtained, repeat the multivariate curve decomposition (step S103~S108). Thus, based on the obtained boundary value, it is possible to determine the number of components contained in a sample more accurately and easily (step S113).
