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
Triazine anticoccidial drugs are a new type of anticoccidial drugs, and daily tests involve livestock and poultry and feed samples. This article, simplified from SN/T 2318-2009, is an instrumental method for rapid detection of four triazine anticoccidial drug residues, quantified by internal standard method.
Pretreatment
For related reagent materials, standard configuration and reserves, and sample preparation methods, please refer to the above standards. For related instrument methods, please refer to this document. ( TSQ Triple Quadrupole Mass Spectrometer Concise Application Manual - Food Safety Testing )
instrument
The TSQ Triple Quadrupole LC/MS system is equipped with an ultra-high pressure liquid phase system.

in conclusion
In the above national standard test methods, the detection limit of triazine anticoccidial drugs in different matrices is 1.0-20.0 μg/kg. The method is fully capable of meeting the requirements of domestic and international regulatory standards for sensitivity and reproducibility of conventional regulatory methods.
