Apparatus of the high voltage a. c. arc source (4400-2A; 2200V-4A) as the light source of spectrographic analysis was designed and manufactured, and the quantitative spectrographic analysis of manganse, titanium, silicon, nickel, chromium, and arsenic in steel was carried out by it. It was ascertained that the quantitative analysis which hsd been impossible for small amount of the above elements in steel in the usual spark discharge method, became possible in high sensitivity and about 3-8 percent reproducibility by the above apparatus.<BR>As for the other characteristic, it was proved that there was practically no continuous background and few loss of testpieces on account of a lower temperature of the electrode.
