spectral quantification method, the spectral quantitative apparatus and program

摘要

Disclosed liquid, the composition ratio of the components of the quantification purposes of the mixture of solid or gaseous, and determines the addition concentration as in the conventional standard addition method without the hassle of measured while changing stepwise. A spectroscopic quantification device 100, the original spectrum and the reference spectra by spectral analysis the standard sample containing a component of the analyzed sample 10 and quantitative purposes, including the components of the quantification purposes unknown composition ratio in known composition ratio a measuring unit 110 to obtain a second generation of generating a first generation unit 130 to generate a virtual additive spectrum with the coefficient a virtual addition ratio of the plurality of types from these spectra, the analyte spectrum of the plurality of types from the virtual additive spectrum parts and, quantification and extracting section 170 the signal intensity profile of the components of the quantitative purpose corresponding to the virtual additive rate by a process including the multivariate analysis, are included from the virtual additive rate dependence of the signal intensity profile in the analyzed sample 10 It includes a determination unit 190 for determining an unknown proportion of the component of interest.BACKGROUND 1
