PROBLEM TO BE SOLVED: To provide an ICP emission spectral analysis method for easily, efficiently and accurately implementing a quantitative analysis of an element to be measured, even if a sample solution to be measured contains elements other than the element to be measured.;SOLUTION: In the ICP emission spectral analysis method, components within the sample solution are excited by introducing the sample solution into a high frequency plasma, after the sample solution is nebulized, each element emits a light with a characteristic wavelength, and quantitative analysis of the elements inside the sample solution is implemented, based on emission spectra obtained by separating the light. The same element other than the element to be measured is added to both a standard sample solution having the element to be measured with a known concentration and the sample solution to be measured so that they are at the same concentration. Quantitative analysis of the to-be-measured element to be measured is implemented, based on emission intensities of the element to be measured in both solutions.;COPYRIGHT: (C)2009,JPO&INPIT
