Abstract
FIELD: metrological provision of analytic control of harmful gasses in the air. SUBSTANCE: solution with given concentration of uranium hexafluoride in freon-113 is placed in vessel of apparatus for production of standard gas mixture. Solution using wick is fed into mixing volume and evaporated. Vapors are mixed with nitrogen flow evaporated from liquid phase. Concentration of uranium hexafluoride in gas mixture is determined by measurement of solution losses from vessel. Apparatus body is made of transparent leucosapphire. It has vessel made in the form of measuring cylinder, measuring in doses member made in the form of tube with wick of fluorolon fabric and mixing vessel. EFFECT: method and apparatus allow to create standard of gas mixture bearing uranium hexafluoride. @ cl, 1 dwg, 1 tbl
