现代工业,如化肥、石油化工、有机及高分子化工、高能燃料、电力、宇航、原子能、医药等,往往需要监测原料及产品中的痕量水分,有时甚至低达 ppb 级。如硫酸工业中,进入转化炉前的 SO_2,含痕量水可腐蚀热交换设备,同时影响催化剂的活性和机械性能;在烯烃聚合、特别是高效催化剂的使用,应严格控制水分含量;对高能燃料的生产、储存及使用中,都必须严密监测其中的水分;液晶、胰岛素、叶录素中水分子与其性能和结构有着密切的关系;有些由于痕量水分参与了化学反应影响了主成分的性 Modern industries, such as chemical fertilizers, petrochemicals, organic and polymer chemicals, high-energy fuels, electricity, aerospace, atomic energy, medicine, etc., often need to monitor traces of moisture in raw materials and products, sometimes even as low as ppb. Such as sulfuric acid industry, into the pre-converter SO2, containing traces of water can be corrosive heat exchange equipment, while affecting the catalyst activity and mechanical properties; in the polymerization of olefins, especially the use of highly efficient catalysts, should be strictly controlled moisture content; high energy The production, storage and use of fuel must be closely monitored. The water molecules in liquid crystal, insulin and sporophycin are closely related to their performance and structure. Some of them are involved in the chemical reaction due to trace amounts of water and affect the main components Sex
