A quantitative spectrometry apparatus 100 includes a measurement unit 110 that spectroscopically analyzes an analysis-target sample 10 containing a component targeted for quantification in an unknown composition ratio and a reference sample containing the component targeted for quantification in a known composition ratio to obtain an original spectrum and a reference spectrum, a first generation unit 130 that generates, from these spectra, hypothetical addition spectra including a plurality of hypothetical addition rates as coefficients, a second generation unit that generates a plurality of analysis-target spectra from the respective hypothetical addition spectra, an extraction unit 170 that extracts a signal intensity profile of the component targeted for quantification corresponding to the hypothetical addition rates by performing a process including multivariate analysis, and a determination unit 190 that determines the unknown composition ratio of the component targeted for quantification contained in the analysis-target sample 10 from the dependence of the signal intensity profile on the hypothetical addition rates."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method for quantitative spectrometry, quantitative spectrometry apparatus, and program","description":"A composition ratio of a component targeted for quantification in a liquid, solid, or gaseous mixture is determined without taking the effort of performing measurement while stepwise changing an addit","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9791373","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
