The report describes a technique whereby very small amounts of mixtures of inorganic compounds, commonly found in primers and detonators, can be analyzed quantitatively by means of the polarograph. Investigations were confined to a typical mixture composed of potassium chlorate, cuprous thiocyanate, antimonous sulfide stibnite, and lead azide, and mercury fulminate. The mercuric fulminate was analyzed by dissolving it in a concentrated hydrochloric acid, boiling to remove hydrogen sulfide, dilution to a volume of 100cc, which was 1 M in free hydrochloric acid, and recording te polarograph. Analysis of the lead azide for lead content was made in the same manner as that for mercury in mercuric fulminates. The azide ion was determined cerimetrically.
