This article analyzes the problems of instrument detection limits not meeting actual needs in pesticide residue detection,severe interference from impurities in the pre-treatment process,and difficulty in obtaining standard substances.Optimization measures such as using high-sensitivity detection technology,introducing high-performance liquid chromatography purification technology,and establishing a complete standard substance database are proposed to improve detection accuracy and reliability,and ensure the quality and safety of grain and oil.
