“…When a 10-ml. sample of ethylene dichloride was treated with 20 pellets of sodium hydroxide no sodium could be detected by flame photometry in the ethylene dichloride fraction (11). Since sodium can be detected in the concentration of 0.01 microgram per milliliter, it is unlikely that our method of purification of the urinary extract depends upon the solubility of sodium hydroxide in ethylene dichloride.…”

A simple highly sensitive flame-photometer was built. Ir eonsists of a hydrogen-oxygen flame, a glass prism monochromator anda multiplier phototube (type 931A of IP22).The sensitivities of the measurements were: 0,6 p. p. m. for barium, 0,2 p. p. ra. for strontium, 0,09 p. p. ra. 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 ana]ysis of K~SiO 3 solutions.A simple method is described for treating the interference effeets of Ba, St and Ca.

“…The attractiveness of the flame photometer as a means of determining sodium and potassium is greatly enhanced by the intelligence that the very large errors involved are due largely to improper instrument design which is remediable (8). The most desirable range is found to be 0-10 ppm., allowing water to be analyzed without concentration.…”
