1. Purification and separation of noble gases

1.1 Purification benefits

Using chemical and physical adsorption processes, the purification and separation of noble gases eliminates the need for all polluting species (N ₂ , H ₂ , C _x H _y , H ₂ O, etc.) to be present in a purification line with regard to noble gases (isobaric interference, pressure effect) and the enclosure (memory effect). These two steps should ultimately lead to the following improvements.

– Introduce into the analyzer a pressure compatible with that required for mass spectrometry in static mode, i.e. 10 ^...
