A new technique for the gas chromatographic analysis of labeled organic compounds has been developed. The method is based on the interruption of the elution, in a suitably designed gas chromatograph, which allows each radioactive peak to be individually trapped within a large volume detector, to be counted for a time which is much longer than in the conventional, continuous-flow analysis. The advantages of the new method and its application to the analyses requiring the combustion of the radioactive effluents are discussed.
