Abstract
A qualitative analysis is carried out by first storing reference spectral line data of various elements in different compound forms, exciting a sample and spectroscopically analyzing signal light emitted from the sample to obtain measured spectral line data, determining whether these measured spectral line data include spectral lines of specified compound-forming elements, and comparing the reference spectral line data with the measured spectral line data, if the measured spectral line data are found to include spectral lines of any of the compound-forming elements, to thereby identify elements in the sample.
