5. Conclusion
This article describes in detail the ultra-high vacuum chemisorption and physisorption processes used to purify and separate noble gases. These two distinct processes, one reversible, the other not, ultimately enable each noble gas to be isolated independently of the others, and measured by mass spectrometry under optimum analytical conditions. Future improvements in purification methods will probably be linked to technological advances in the development of new adsorbents, as suggested by the work of Barnerjee et al., who are studying the separation of krypton and xenon using organometallic compounds
