Abstract： The matrix effect leads to the enhancement or inhibition of the response in the instrument with the components to be determined， which affects the accuracy of the qualitative and analysis of the substances to be measured. The main factors of matrix effect include pigment， acrid substance， acid-base property，sample uniformity， consistency of the sample with the matrix， etc. The structure and stability of pesticides will also affect the accuracy of qualitative and quantitative results. The impact of various factors on GC-MS/MS should be fully considered in the inspection of pesticide residues.

Keywords： matrix effect; main factors; qualitative; quantitative
