Abstract
A quantitative analysis of the constituents in a specimen and being classified by the conditions of the constituents in the specimen, using a spectroscopic analysis is made by exciting the specimen a number of times for emission, detecting the light intensity data of the line of the constituent element and the non-constituent element of the specimen per emission, storing the light intensity data of the lines specifying emission which contains the constituent element and the non-constituent element over a predetermined level based on the stored data, and determining that there is present a composition of the constituent element and the non-constituent element at a portion of the specimen corresponding to the specified emission.
