Determination of benzoylurea pesticide residues in food--Liquid chromatography-tandem mass spectrometry
Food safety analysis workflow
Thermo Scientific Life Science MS not only has a long tradition of technology, but also continues to innovate. Quadrupole mass analysis of true conjugate hyperboloids that fits the perfect theoretical electric field of a textbook is used on all TSQ® triple quadrupole mass spectrometers. Since launching the world's first triple quadrupole MS/MS (TSQ®) mass spectrometer in 1980, TSQ® triple quadrupole mass spectrometer has been widely used in environmental protection, agriculture, quarantine, food safety, etc. Analytical testing, fully capable of testing routine testing of large-volume samples of crops, livestock and poultry products, dairy products and related processed foods, such as pesticide residues in food, veterinary drug residues, mycotoxins, additives, nutritional supplements and organic pollutants And other projects to help you easily meet the increasingly stringent regulatory requirements.
TSQ® Triple Quadrupole Mass Spectrometer and Thermo Fisher Food Safety Testing Strategy
summary
Benzoyl urea insecticides are a class of specific insect growth regulators that are low-toxic, highly efficient, and widely used. This paper has developed an instrumental method for rapid detection of various benzoylurea insecticides with reference to SN/T0528-2012 and SN/T 2540-2010, and quantified by external standard method.
