A simple highly sensitive flame-photometer was built. It consists of a hydrogen-oxygen flame, a glass prism monochromator and a multiplier phototube (type 931A or IP22). The sensitivities of the measurements were: 0,6 p. p. m. for barium, 0,2 p. p. m. for strongtium, 0,09 p. p. m. for calcium and 0,005 p. p. m. for potassium. The flame-photometer was developed for the simultaneous determination of Ba, Sr and Ca content of oxide coated cathodes, and for the potassium analysis of K2SiO3 solutions. A simple method is described for treating the interference effects of Ba, Sr and Ca. The problems of sensitivity improvements are discussed.
