一、前言微量水分析对发展国民经济、增强国防、实现四个现代化具有重要意义。在三大合成材料中,例如聚合人造橡胶,必须把单体及溶剂的水分控制在20 PPM(百万分之一)以下,否则会引起挂胶、催化剂中毒而停产;在电力部门,分析控制变压器油中的微量水含量,可预测高压和超高压变压器的潜伏性故障;我国正在研制的大功率新型蒸气发电机是采用氟里昂冷却的,也必须严格控制其水分在几十 PPM 以
I. Preface Trace water analysis plays an important role in developing the national economy, enhancing national defense and realizing the four modernizations. In three synthetic materials, such as polymerized elastomers, the monomer and solvent must be kept below 20 PPM (parts per million), otherwise they will stop gumming and catalyst poisoning. In the power sector, the analytical control Transformer oil in the trace of water content, high pressure and ultra-high voltage transformers can predict the potential failure; China is developing a new high-power steam generator is Freon cooling, it must also be strictly controlled its moisture at tens of PPM to
