Modern industry, such as fertilizers, petrochemicals, organic and polymer chemistry, high-energy fuel, electric power, aerospace, atomic energy, medicine and other raw materials and products often require monitoring of trace moisture, and sometimes even as low ppb level. Such as sulfuric acid industry, transformed into the blast furnace SO_2, containing traces of water can corrode the heat exchange equipment, and mechanical properties affect the activity of the catalyst; polymerization of olefins, especially the use of efficient catalysts, should strictly control the moisture content; High Energy production, stockpiling and use of fuels, which must be closely monitored moisture; liquid crystal, insulin, prime leaf water molecules in its record performance and structure closely related; some traces of water due to the influence of the chemical reactions involved in the main component sex.
Tengzhou City Technology Co., Ltd. Xiangying analysis developed GC7990plus gas chromatograph, success was measured traces of water with satisfactory results.
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。
滕州市翔鹰分析技术有限公司研发出GC7990plus气相色谱仪，成功测定了痕量水，结果满意。
