Abstract: This study analyses the main challenges faced by high performance liquid chromatography-mass spectrometry in the detection of pesticide residues in food, including insufficient sensitivity, limited quantitative accuracy and complex matrix interference. By optimizing sample pretreatment method, improving chromatographic separation conditions and innovating mass spectrometry detection parameters, an analytical scheme combining matrix solid phase dispersion extraction and isotope internal standard method was proposed, which was helpful to improve the sensitivity and accuracy of agricultural residue detection.

Keywords: liquid chromatography-mass spectrometry; pesticide residues; matrix effect
