This paper describes the use of spectrographic methods in attacking some of the problems encountered in the manufacture of radio tubes. Illustrations of the laboratory and apparatus are discussed. The techniques and use of qualitative spectrographic analysis in connection with chemical, metallurgical, ceramic, and fluorescent problems are described and illustrations of the application of quantitative spectrographic analysis to problems of routine inspection and control are given.
