In response to the urgent need for on-line monitoring technology in the production, storage, and use of large quantities of toxic and volatile organic chemical solvents in China, Dr. Li Haiyang’s research team at Dalian Institute of Chemistry developed an on-line monitoring technology for important organic chemical solvents based on ion mobility spectrum technology. And complete sets of equipment. The reporter learned from the Dalian Institute of Chemicals on the 8th that the national "863" project has passed the acceptance of the Ministry of Science and Technology, which means that China's volatile chemicals are expected to be monitored in real time. According to Li Haiyang, the equipment is more functional than similar equipment in foreign countries, and the price is lower than similar foreign equipment. Its various technical and economic indicators have reached the international advanced level, with extensive application and promotion value. The project has applied for 11 invention patents and 2 software registrations. The complete set of equipment they developed achieved on-line monitoring of chemicals such as methylene chloride, acetone, acetic anhydride, dimethyl sulfoxide, acrylonitrile, acrylates, benzene, phenol, and p-xylene, with a single measurement response time of less than 3 Second, the minimum detection limit is less than 0.05ppm; the development of a new type of high-efficiency atmospheric glow discharge ionization source and UVRI ionization source is a domestic and foreign initiative, with original innovation. In addition, the chemical agent alarm device developed by the project team played a role in national defense construction; the explosives and poison detection instruments developed were used for the Beijing Olympics security and the Shanghai World Expo security; the project team also developed an insulation switch for the Chongqing Electric Power Academy. The online SF6 purity monitor developed an on-line measurement instrument for anesthesia in surgery for Harbin Medical University. It is reported that during the implementation of the project, international cooperation has played an important role. Dahua Institute cooperates with ORNL in ground-based on-line measurement technology for ground-based chlorine-containing VOCs based on ion mobility spectrometry. ORNL provides US$100,000 for personnel exchanges and development of novel ion-transfer tubes and their components. . As China’s overall national strength has risen and industrial modernization continues to advance, the production safety of enterprises has become increasingly important. The toxic gas monitor is an important national high-tech protective equipment. Organic chemical solvents have a very strong volatility. A large number of toxic and harmful organic substances leaked during production, use, and storage can cause serious harm to the human body and the natural environment. The development of rapid, real-time on-site monitoring technologies and equipment can help The safe production and application of organic chemical solvents during production, storage, and use can meet the urgent need for on-line monitoring technologies for large hazardous volatile organic chemical solvents in China.
