Direct reading spectrometer combined with spectrograph has been devised for both quantitative and qualitative spectrochemical routine analyses.<BR>Paschen and Runge mounting of 2.2m concave diffraction grating is used, and 10 exit slits and photomultipliers for direct reading analysis of alloying constituents of steel, and 100 feet roll film camera for qualitative analysis are provided for the spectrometer. Fundamental investigation of high alloy steel analysis by the fully automatic high precision process is described.
