Online monitoring of toxic and harmful gases to achieve technological breakthrough

From March 8th to 14th, at the “Eleventh Five-Year” national major scientific and technological achievements exhibition held at the Beijing International Convention Center, the Continuous Online On-line Monitor for Toxic and Harmful Gases developed by Dalian Institute of Chemicals, Chinese Academy of Sciences, “strengthening basic research and cutting-edge technology research, The unit to enhance the ability to continuously innovate in technology was unveiled and attracted people to stop. This type of instrument that can continuously and accurately detect a variety of organic chemical solvents and chemical warfare agents is currently unique in the world, and customers have signed purchase contracts with Dalian Institute of Materials on the spot.

At present, most of the poisonous and harmful gas detection instruments that are available in the world are aimed at certain single gases. Most detection methods are after the incident. The continuous on-line monitoring device for toxic and harmful gases developed by Dahua can realize 24-hour monitoring of toxic and hazardous gases. Li Ocean, head of the expert group of Dahua University, told the reporter that this instrument is very sensitive and can detect many toxic and harmful organic compounds and chemical warfare agents in the air, such as benzene, toluene, xylene, acrylate, dimethyl sulfoxide. , ***, etc., an instrument can monitor eight sites at the same time, and the network can be used to continuously monitor the regional air environment with a measurement cycle of less than 5 seconds. The instrument can also perform continuous online monitoring during the production, storage and transportation of volatile chemicals.

According to Li Haiyang, the continuous on-line monitoring device for toxic and harmful gases developed by Dahua has obtained more than 30 patents for inventions, and the effective function is obviously higher than similar imported equipment, and the price is 30% lower than that of imported similar products. This set of equipment not only has the strength to compete with the developed countries, but also will drive our country's security to detect the overall development of high technology.

As China’s overall national strength has risen, the development of modernization of national defense and the armed forces, and the development of industrial modernization have continued to advance, the safety of public places, and the safety of corporate production have become increasingly important. Toxic gas monitors have therefore become a matter of national long-term development. **** Important high-tech protective equipment was listed as a national "863" key project.

Under the support of the "863" special online monitoring technology and equipment for organic chemical solvents used by the Dalian Institute of Chemical Physics, the Chinese Academy of Sciences, the high-tech integration application and industrialization demonstration are planned as a whole. The use of array ion mobility spectrum technology with independent intellectual property rights has successfully developed toxic and harmful Gas continuous online monitor. The monitor can be widely used in places such as defense, airports, railways, hypermarkets, and petrochemicals that are prone to toxic gas or toxic gas leakage, and these sites are continuously monitored for a long time.
