Method and device for measuring permeation

A mixture of target isotopic gases, which permeation through a material (F) is sought, is formed in a mixing enclosure. Each isotopic gas has a mass number different from that of the corresponding target gas. A chamber (11) of a permeation enclosure (10) filled with the gas mixture is separated from...

Zusammenfassung:	A mixture of target isotopic gases, which permeation through a material (F) is sought, is formed in a mixing enclosure. Each isotopic gas has a mass number different from that of the corresponding target gas. A chamber (11) of a permeation enclosure (10) filled with the gas mixture is separated from another chamber (12) by the material. The isotopic gases permeating through the material and being present in the second chamber are analyzed simultaneously to simultaneously calculate permeation through the material of each of the corresponding target gases. Independent claims are included for (1) device for measuring gas permeation through a material; (2) method for using permeation measurement device.
