High Purity Gas Production

The modern technologies in radio-electronics, cryogenic, laser, space techniques, medicine demand more and more high-purity gases, making more and more strict requirements under the concentration of the micro impurities. The technology of production of high-purity gases demands modern analytical methods both for operative control of technological process, and for quality assurance of raw materials, intermediate and end products.

The process mass spectrometry is the method which allows solving problems of analytical control at all stages of the high-purity gases production. The basic advantages of a method:

• High speed of the analysis — operative control of the technological process in the several points by one device;

• The simultaneous multi-component analysis in the wide dynamic range – determination of the basic components and micro impurities of the gas mixture for the one cycle of measurements;
  
• Low detection limits – determination of micro impurity and ultra-micro impurity without the enrichments stages;
  
• The isotope analysis — control of the technological process of the gases of spectral cleanliness production.
