The paper describes a new efficient cryoadsorptive method of dihydrogens p-H2, o-H2, HD, o-D2, p-D2, HT, DT, T2 separation with moving temperature gradient on the adsorbent fixed bed. The method was developed at the Department of Chemistry, Moscow State University, as a result of many years’ experimental and theoretical investigations. The separation method, and corresponding periodical action apparatus named MTGA (Moving Temperature Gradient Adsorption), and MGU DETRA (Multispecious Gas Separator-Upgrader: DEuterium, TRitium, Adsorption), respectively, are applied to prepare individual dihydrogens in very pure isotopic or nuclear-spin forms. In this paper, the basic design and possibilities of a typical three – stage laboratory adsorption separative cascade are given. The cascade was used to prepare two gases of ultrahigh isotopic purity (99.9998 mol.% deuterium and 99.98 mol.% deuterium hydride HD) for the first time. Moreover, the paper presents the results of successful studies on enriching microquantities of tritium-containing molecules HT, DT, T2 from macrocomponents H2 and D2.
