In this study, we examined the quantitative-analysis method of Mg Alloy using a photoelectric emission spectrochemical analysis. The analytic wavelength of emissions and the analytic conditions were determined using a standard sample of Mg alloy. Changing the discharge voltage of Zn to 18kv enabled us to obtain useful data. Working curves were formed by correlating the intensity of the emission with the mass%. The accuracy and precision were statistically calculated. The accuracy of the quantitative analysis of major elements in Mg alloy was within 5%. The precision was within 5% in relative error. This analysis determined the quantity of chemical elements of Mg alloy in only 15 minutes. It confirms the practically of this analytical method.
