Introduction: China's first ion mobility spectrometer for on-site rapid detection of food safety debuted at the Chongqing Food Festival on the 28th. According to reports, this machine, which is only the size of a copier, can detect more than 20 kinds of national regulations such as melamine in two minutes and it strictly prohibits artificial addition of substances in fruits and vegetables, meat and other foods.

At the food festival site, Ma Jun, head of ion mobility spectrometer research and development, demonstrated to the reporter how the instrument was used. He readily picked up a small piece of fresh beef from the sales counter and ingested one of them into the machine's storage bin. The ion migration spectrum of the beef was shown on the interface. At the same time, the result that has been automatically compared with the standard spectrum by the computer was shown: “The product you tested meets the inspection standards and related to the Ministry of Agriculture. standard".

The instrument was developed and manufactured by Wuhan Sengan Science and Technology Co., Ltd. After chemical substances are vaporized and ionized, an ion mobility spectrum is obtained. Then the migration spectrum is compared with the standard map determined by the agricultural department, and the inspection is promptly detected. The presence of pesticide residues, veterinary drug residues, lean meat extract, melamine, etc. in food.

It is understood that most of China's current food safety testing equipment is laboratory-grade, not only expensive, but also requires preprocessing for hours or even more than ten hours for almost all inspection items. This has made it difficult to use it extensively in food production, distribution, and sales. The lack of detection methods has become one of the most important causes of food safety accidents.

Zhang Wei, chairman of Wuhan Sengan Technology Co., Ltd., stated that ion mobility spectrometers have advantages in this area: small size, light weight, and can use ordinary power supply to work under atmospheric pressure without requiring pretreatment of the submitted inspection items. The total inspection time was reduced to less than two minutes.

In addition, the on-site rapid detection of ion mobility spectrometers makes it possible for food companies to monitor the entire process of production. Chongqing Cattle Source Beef Products Co., Ltd. is the first enterprise user of ion mobility spectrometer. Xie Deming, general manager of the cattle resources, said: “From pasture, feed, slaughtering, deep processing, and terminal sales, we use ion mobility spectrometers to monitor and eliminate all potential food safety hazards, so we can make a public commitment to the entire society. The safety of beef cattle products."

According to Zhang Wei, achieving full-process monitoring has another significant significance for promoting food safety. He said that ion mobility spectrometry supplemented by two-dimensional bar code automatic identification technology and cloud computing technology, to build a food safety monitoring and real-time traceability system covering the entire society, in order to seek a fundamental solution to food safety issues.
