ABSTRACT:
A quantitative analytical method with spectrometric analysis, wherein a sample is irradiated with light, and a plurality of ingredients contained in the sample to be measured are quantitatively determined on the basis of absorptivities at a plurality of appointed wave number points in an absorption spectrum obtained at that time. An assumed concentration-operating matrix is obtained from a combination of reference spectra for a plurality of ingredients, of which the concentrations have been known, and is previously prepared. The concentrations of the respective ingredients to be measured are calculated by the use of the concentration-operating matrix, thereby capable of carrying out a quantitative analysis in a short time with high accuracy.
