The future of portable GC/MS is promising

At present, the domestic portable GC/MS is nothing more than these three brands, the United States TORION, the United States Inficon, China Concentrate Technology. Other brands of “portable” GC/MS instruments are actually vehicle-mounted. Xiao Bian from the portable GC-MS design intent, main application scope and application examples will explain to everyone what is called "portable" GS-MS.

The original design of portable GC/MS

With the development and application of a variety of high-tech technologies and new materials, many products are moving toward a more lightweight, faster, and simpler operation. When an accident occurs, there is an unexplained substance leak. It takes 2-3 days for the laboratory GC/MS to produce output from sampling to test results. In other words, it takes 2-3 days for the management part to get The basis for decision making. The loss caused by this 2-3 days may be immeasurable. In the context of such technology and demand, the people proposed the design requirements for a portable GC/MS. The primary purpose of the portable GC/MS is to be portable, lightweight, fast in response, simple in operation, and guaranteed to obtain effective data that can support decision-making in the shortest possible time in order to minimize losses.

Application of Portable GC/MS

The application of environmental emergency detection has proved that China's environmental pollution is closely related to the rapid development of China's heavy industry. There may be accidents in the production, transportation and storage of this industry, resulting in various types of toxic and harmful volatile organic gases, spreading over large areas, and causing sudden environmental pollution accidents. Portable GC-MS performs accurate qualitative and quantitative analysis of volatile and semi-volatile organic compounds at the scene of an accident, and has a high sensitivity, so it occupies an increasingly important role in the detection of emergency environments.

Customs applications The Customs conducts inspections on imports and exports, mainly on the detection of dangerous goods and explosives. Detection requirements can respond quickly. The portable GC-MS sample analysis takes only 3-5 minutes and is easy to transfer, making it ideal for customs inspections.

Applications for food safety The QC department can use portable GC-MS to quickly detect the presence of volatile or semi-volatile harmful components in foods. Detection is quick and simple. Sampling inspections can be performed at any time in the food production department, and the results can be produced on the spot, shortening the regulatory cycle. The TORION Portable Gas Chromatography Unit of the United States can also quickly detect pesticide residues in fruits and vegetables.

Other applications: arson investigation, criminal investigation scene investigation, disease control center, etc. Portable GC/MS on-site emergency case In Jiangsu Province, in a sudden organic pollution incident in 2006, a tanker carrying 30T liquid dangerous goods (styrene) was turned over. Some of the transported substances leaked into the farmland, and portable GC-MS on-site inspections achieved good results.

In 2008, the “7.17 Fengxian Fire” incident in Shanghai used portable GC-MS on-site inspection and reported monitoring data to the on-site command in the first time, which provided decisive data for the commanding department to determine the scope of evacuation.

In 2009, there was an unpleasant odor odor in the soil on the outside of the Panpan Food Factory in Chengdu. The Chengdu Environmental Monitoring Center used a portable GC-MS to analyze the unpleasant malodorous gas and determined that the main component of the malodorous gas was tetrahydrothiophene. The whole process was fast and accurate. The environmental management department has decided to isolate the area and formulate the treatment plan for a great deal of initiative, thus bringing great convenience to the timely handling of environmental accidents.

Portable GC/MS Market Outlook

After the Songhua River incident in 2005, portable GC/MS instruments began to enter China and were taken seriously by the Chinese government. Many provincial and provincial environmental monitoring stations have begun to deploy portable GC/MS instruments under the strong support of the government. With environmental issues increasingly attracting attention from the government and the people, the government has continuously increased its investment in environmental protection. Recently, many environmental monitoring stations in prefecture-level cities have begun to deploy portable gas-mass spectrometers. Emergency monitoring capabilities will be further improved. At present, the author has learned that there are still many city-level county-level environmental monitoring stations in China that are equipped with or will soon be equipped with a portable GC/MS.

For the special scene of environmental emergency monitoring, the portable-fast-easy-to-use-reliable portable GC/MS is more suitable for the complex environment. The author hereby recommends Terry's TRIDION-9 portable GC/MS. This instrument is the only one based on on-site testing as the basis for the design of the instrument, algorithm and structure are in line with the needs of the rapid analysis results of on-site testing. It is said to be the world's lightest and most responsive device for an environmental emergency site.

The author concludes that miniaturization and portability are new trends in the future development of analytical instruments, just as computers have shortened the palm of your hand from a large area. The TERI TRIDION-9 portable GC/MS instrument based on field detection is widely used in China.
