Abstract: A method and apparatus for separation of an isotope mixture of hydrogen, sting predominantly in molecular form and/or inbound form, from the remaining components of a gas. A first chamber is separated from a second chamber by a wall which is permeable for atomic hydrogen and less permeable for molecular hydrogen. The hydrogen is converted into atomic hydrogen or, if necessary, is separated in atomic form from the material with which the hydrogen has gone into chemical composition. A device electrically operable independently of the wall is provided for converting the molecular and/or bound hydrogen to form atomic hydrogen in apparatus for this purpose. A heating device for elevating the temperature of thread, wire, or body of other form capable of being heated above 1500 K is provided and such thread, wire, or body is made of high-melting material, such as tungsten, iridium, osmium, or rhenium.

Abstract: An apparatus utilized for separating hydrogen isotopes from a gas mixture separate isotopes contained in a hydrogen isotope mixture. The apparatus is provided with two chambers closable by valves and surrounded on all sides by walls and separated from each other by a wall or partition of material differing from palladium though permeable preferably for atomic hydrogen and permeable only to a lesser extent for molecular hydrogen. One of the chambers is connected with a gas supply line as well as a gas discharge line, and the other chamber, provided for collecting isotope mixture coming through the permeable wall, is capable of being evacuated. The remaining walls of the chambers consist of material which is not or is only poorly permeable for hydrogen isotopes.
