Determination method for Fluralaner residues in animal-derived food and application of determination method for Fluralaner residues in animal-derived food

The invention belongs to the technical field of medicine detection, and discloses a method for determining Fluralaner residue in animal-derived food and application of the method, and the residual quantity of Fluralaner in a sample is accurately and efficiently determined by utilizing a solid-phase extraction pretreatment technology. The method includes: preparing a standard stock solution, extracting a target object, carrying out solid-phase extraction, carrying out qualitative determination and quantitative determination through liquid chromatography-tandem mass spectrometry, injecting a sample solution into a liquid chromatography-tandem mass spectrometer in an optimal working state of an instrument, measuring a corresponding peak area, and obtaining the concentration of the Fluralaner in the sample through a standard curve. According to the method, the solid-phase extraction pretreatment technology is utilized, the residual quantity of the Fluralaner in the meat and animal-derived food can be effectively
