  • Method and apparatus for destroying organic matter to facilitate trace inorganic element analysis
    Patent number: 4255386
    Abstract: The apparatus of the present invention includes a quartz flask for containing 71% nitric acid and the organic matrix to be destroyed, a Soxhlet extractor disposed above the flask, and a Friedrich coldfinger reflux condenser disposed above the extractor. A Meeker or Fisher burner is employed to provide heat to the flask and distill the acid, and the vapors are condensed within the condenser and transmitted to the extractor. An adjustable volume displacement cylinder is disposed within the extractor so as to control siphoning of the acid condensate from the extractor back into the flask. The distillation-condensation-siphoning procedure of the present invention is automatically operative once the displacement cylinder is adjusted. The organic matrix is completely destroyed so as to produce a clear, colorless acid solution within which the trace inorganic salts are disposed. The acid solution may be subsequently qualitatively and quantitatively analyzed in accordance with known techniques.
