Mixtures on basis of rare gases: application and methods of production.

Neon, helium and heavy rare gases possess a number of unique properties and can be a part of various mixtures used in lasers, welding process, diving, medicine and precision engineering. The basic methods of preparation of compound substances with specified concentration of components, including rare gases and their stable isotopes are considered in the work. The examples of the mixtures components amounts obtained by manometric and gravimetric methods are given. The areas of potential preferred use of volume and flow mixers are shown. Industrial and laboratory methods of mixtures preparation in the form of cryogenic liquids are also studied in the research.
