Isotopic Analysis of H$sub 2$, HD, D$sub 2$ Mixtures and Analysis of Ortho- Para-Hydrogen Mixtures by Gas Chromatography; DOSAGES PAR CHROMATOGRAPHIE EN PHASE GAZEUSE DE MELANGES D'HYDROGENE, D'HYDROGENE DEUTERE, DE DEUTERIUM ET DE MELANGES ORTHO-PARA-HYDROGENE

The possibilities of vapor phase chromatorgraphy for the separation and analysis of mixtures of H/sub 2/, HD, and D/sub 2/, and of ortho- and para- hydrogen mixtures are described. Separation factors for physical adsorption of the various varieties of hydrogen were deduced from chromatograms and were also measured directly with a static method. The agreements are good. (auth)
