METHOD FOR ESTIMATING DENSITY AND PURE SPECTRUM FROM COMPOUND

摘要

PURPOSE: A method for estimating density and a pure spectrum from compound is provided to estimate pure spectrum and density of components included in compound by applying principal component analysis and independent component analysis for a spectrum of compound. CONSTITUTION: A method for estimating density and a pure spectrum from compound analyzing principal components for n spectra of compounds measured by using m number of wavelengths so as to represent the main components a score(11). The number of components to be used is selected(13). Independent component analysis is performed(15). Pure spectra and density are estimated by performing independent component analysis.
