Air Separation Equipment - Determination of Nitrous Oxide in Liquid Oxygen for Gas Chromatography

      Nitrous oxide (N2O) commonly known as nitrous oxide, is a colorless, microstrip sweet, non-flammable, non-irritating gas, but also a greenhouse gas. The relative molecular weight of nitrous oxide is 44.20, the three-phase point is -102.4 ℃ and the boiling point is -89.8 ℃. At room temperature, the chemical properties of stable, soluble in ethanol, oil and ether. The content of nitrous oxide in the air is very small, about 0.3 ~ 0.4μL / L.

      The content of nitrous oxide in the liquid oxygen of the condenser of the air separation plant was monitored. The practical application shows that this method has the advantages of accurate analysis, short process time and good stability.

       Tengzhou City, the vast chromatographic equipment Technology Co., Ltd., advancing with the times to scientific development as a guide, under the leadership of Wang Xiaoying manager, relying on Xiangying Institute of Analytical Technology, Institute of Chromatography, analysis and testing center, three scientific research units , The development of air separation equipment in liquid oxygen nitrous oxide analysis of special gas chromatograph, the success of the determination of trace N2O content, the results were satisfactory.
