Problems of quality check while producing helium 99.9999%.

Author(s) : BONDARENKO V. L., LOSYAKOV N. P., SIMONENKO Y. M., et al.

Summary

The requirements of the world's largest companies to the quality of helium have been generalized. The difficulties of the micro-impurities estimation by a chromatographic method have been noted. The methods of the high-purity helium industrial production from the neon-helium mixture that is obtained from the ambient air have been described. The research results have allowed producing technical and high purity helium in the amount of tens of thousands of m3 per year as well as preserving and returning thousands of cubic meters of neon to the processing.
