A new method by which the component elements: C, H, O, and N, in an organic compound can be simply, rapidly, and economically identified was established on the basis of the reaction of an organic compound with sulfur at atmospheric pressure. The apparatus for this method consists of two gas chromatographs and an original reactor for reacting an organic compound with sulfur vapor. One component separated from a given mixture by the use of one gas chromatograph was made to react with sulfur vapor in the original reactor and then the reaction products were analyzed by the use of the other gas chromatograph. The reaction products were restricted to seven kinds of compounds irrespective of the chemical structure of the target component. According to this method, the component elements: C, H, O, and N, in an organic compound could be easily identified by the reaction products within 20 min with a detection limit of a few pmol.
