Under the same experimental conditions, the mass retention time of the substance to be tested in the sample was the same as that of the mixed matrix standard solution and the background The selected ions in the sample mass chromatogram showed a comparison of the abundance of the selected ions compared to the mixed substrate standard solution. If the value is within the allowable range (the allowable range is shown in Table 3), it is determined that there is a corresponding analyte in the sample. Under the above chromatographic conditions, The retention time of pesticides and their monitoring ions (m/z) are given in Appendix B, Table B.2.
