Abstract A method is described for separating deuterium in hydrogen streams at 30 to 70% deuterium. The method is based on thermal conductivity for sensitivity and simplicity. A gas chromatograph equipped with a gas-sampling cell was used to analyze small (5 to 10 ml) samples. Small air leaks into the system resulted in a need for a column packing to separate deuterium from air or to separate the three components deuterium, oxygen, and nitrogen in the presence of hydrogen. By observing the ratio of O/sub 2/ to N/sub 2/ it was possible to detect whether the leaks that developed were in the sampling system or in the D/sub 2/H/sub 2/ reaction vessel. The separation and experimental details are pre sented from which the D/sub 2/ sensitivity was calculated to be approximately 500 ppm for a 5- ml sample. (B.O.G.)
