employed for the decomposi-
tion of organic compounds, while adequate to bring chlorine, bromine, or iodine completely into ionic form, do not succeed in transforming

In the analysis of organic compounds containing fluorine, or both fluorine and chlorine, the sample is weighed in a gelatin capsule or glass ampoule, and heated with metallic potassium in a nickel bomb at 500° to 550° C. for 2 hours. The bomb is washed out and the resulting solution is made up to volume. Half of this solution is titrated for chloride by the V olhard method. The other half (or less) is analyzed for fluoride by distillation and titration with thorium The method is particularly suitable where nitrate. high accuracy is desired. The bomb method of de
