Abstract
Krypton is a significant natural resource with great importance for modern industry, medicine, and science. This article considers the issue of preserving the purity of this inert gas of various grades, describes the main processes that can affect the amount of impurities in krypton, and highlights its current applications. Experimental data aimed at elaborating questions about the methodology of surface preparation before contact with high-purity krypton are presented. Moreover, the amount of impurities from the time of container preparation for gas grade 5.8 is evaluated, and dependences of moisture content on the method of preparation and type of surface, which is in contact with high-purity gas, are obtained. Further, statistics on filling containers with argon grade 6.0 and its preliminary preparation are collected. For parameter estimation, cylinders with different types of surfaces are used, both unused and with a service life of more than 10 years. The paper shows various parameters that can affect the purity of krypton. Thanks to the data collected during the experiments, the requirements for future works can be adjusted.
