Medium temperature electrolytic fluorination is the main development direction of electrolytic fluorine process at home and abroad. The generated fluorine gas contains impurities such as oxygen, nitrogen, carbon tetrafluoride and hydrogen fluoride because fluorine gas is the production of sulfur hexafluoride and uranium hexafluoride Of the important raw materials, fluorine gas purity will directly affect the level of sulfur hexafluoride and the yield of uranium hexafluoride, it is necessary to analyze the fluorine gas to control the quality of fluorine gas.

      As the fluorine and hydrogen fluoride is highly corrosive, ordinary chromatography equipment, simply can not be used.

       In order to effectively monitor the purity of fluorine gas in the production process, Tengzhou vast chromatographic equipment technical services Co., Ltd., advancing with the times, under the guidance of scientific development, under the leadership of Wang Xiaoying manager, relying on Xiangying Institute of Analytical Technology, chromatography engineering research , Analysis and testing center, three scientific research units, developed a chromatographic fluorine gas purity analyzer. In order to solve the problem of corrosion resistance of TCD and column, a key anti-corrosion gas chromatograph was developed to analyze the purity and impurities of fluorine gas. The spectrometer can accurately determine the purity of fluorine gas and its impurity content.
