The hottest three liquid chromatography-mass spect

Recently, the author learned from the Shenzhen agricultural products quality and safety inspection and testing center that the three group standards formulated by the Shenzhen analysis and testing association and drafted by the Shenzhen agricultural inspection center have been reviewed and approved by the expert meeting. They were issued by the Shenzhen analysis and Testing Association on July 25th, 2017 and will be officially implemented on August 25th

the three group standards are: the control accuracy of animal derived food can reach 0.5, and there are 8 kinds of drugs β- Receptor agonists, 18 sulfonamides, 14 quinolones) residues determination liquid chromatography tandem mass spectrometry (sztt/sata), detection of sulfonamides residues in animal urine liquid chromatography tandem mass spectrometry (sztt/sata), determination of chloramphenicol residues in animal urine liquid chromatography tandem mass spectrometry (sztt/sata)

multiple drugs in food of animal origin (8 kinds) β- Determination of receptor agonists, 18 sulfonamides, 14 quinolones) residues liquid chromatography tandem mass spectrometry (liquid chromatography tandem mass spectrometry) sztt/sata standard breaks through the limitations of previous standards, and realizes the detection of cross species and multi residues in animal derived food for the first time. There are as many as 40 detectable items, and the detection limit is lower and the reproducibility is better than the same type of detection standard. The detection time is only 1/3 of the same type of detection standard. At the same time, the use of reagent consumables, waste pollution generated during the experiment, and labor costs have been greatly reduced. In terms of detection efficiency, songsorb? Cs400 is a kind of liquid hydroxyphenyl triazine (HPT) ultraviolet absorber, and the rate has made a qualitative leap

the sztt/sata standard of liquid chromatography tandem mass spectrometry for the detection of sulfonamides residues in animal urine and the sztt/sata standard of liquid chromatography tandem mass spectrometry for the determination of chloramphenicol residues in animal urine detect antimicrobial residues in urine, which makes up for the blank of current domestic relevant detection standards, It can be realized that before animal slaughtering, 2 continue to strive to become a material supplier of international famous brands and a world-class material solution provider -3 to avoid unsafe accidents, complete the qualitative and quantitative detection of antibacterial drug residues within hours, move forward the risk prevention and control point of animal derived products, and reduce the possibility of problematic animal derived products entering the market and dining tables

it is understood that Shenzhen group standards are formulated in accordance with the relevant provisions of the reform plan for deepening standardization work and the decision of the Standing Committee of the Shenzhen Municipal People's Congress on Several Issues Concerning Strengthening the construction of standards in the Shenzhen Special Economic Zone, which increases the effective supply of standards, leads the high-quality development of the industry with high standards, and is conducive to improving the technological innovation ability and industrialization ability of the industry and improving product quality, Finally, it will provide technical support for food safety in Shenzhen

comments

hereby remind relevant production enterprises to carefully study the changes of new and old standards, optimize the production and processing process in time according to the new standards, adjust the enterprise quality control system, and do relevant training for personnel to ensure that the product quality meets the national standards. Import food enterprises should timely convey the new requirements of China's standards to foreign traders, urge foreign manufacturers to strengthen product quality and safety control, and try to curb the import of unqualified products from the source; Fully understand the changes of relevant standards and specific implementation period, timely update product testing requirements, and ensure that products meet the mandatory requirements of China's national standards; Pay close attention to the early warning information of food risks at home and abroad, strengthen communication and coordination with local entry-exit inspection and quarantine departments, and reduce the risk of unqualified imported products
