A method of direct reading analysis by spark excitation has been developed with Hitachi photoelectric spectrophotometer EPU-2A provided with a small spectrophotometer for measuring the light absorption. Despite the small dispersion of the electrometer, the developed method is found applicable to routine spectrochemical analysis of nonferrous alloys,for their emission spectra are not complicated. Results of analysis on copper alloys of Zn, Sn, Si and Mn are in good agreement with those of
