Multiresidue Analysis of Pesticides in Agricultural Products by GC/MS Coupled with Database Software

Abstract: We evaluated a multiresidue method for determination of pesticides in agricultural products by SCAN mode GC/MS coupled with three kinds of database for 253 pesticides: relative retention time, mass spectra and calibration curve (SCAN method). Twenty-six pesticides, a total of 131 pesticides were detected in samples by the SCAN method. The detection results agreed closely with those of the SIM mode GC/MS method using calibration standards (SIM method). The ratios of the SCAN method to the SIM method ranged from… Show more

“…5 Its effectiveness has been demonstrated by several studies. [7][8][9][10] An efficient extraction method for a wide range of GC-MS-amenable SVOCs is required to take full advantage of the potential of the AIQS-DB system. For water samples, we developed a solid-phase extraction (SPE) method for AIQS-DB by using styrene-divinylbenzene (SDB) polymer and activated carbon cartridges previously.…”

“…24,27,28) Grapefruit was produced by natural crossing pomelo and orange, so it is necessary to note that similar interfering peaks appear over the entire product ions produced from the protonated molecule of imazalil on the chromatograms of the test solution of pomelo by LC conditions. In addition to the MS/MS system, EI-SIM/Scan mode GC-MS, 9) negative chemical ionization (NCI)-SIM/Scan mode GC-MS, 17) dual-column GC-ECD/ECD, 3,11) dual-column GC-FPD/NPD, [4][5][6] ESI-SIM/Scan mode LC-MS with diode-array detection (DAD), 13,14) and HPLC with post-column FLD for residual N-methyl carbamate pesticides, 24,29) were also adopted. Thus, the systematic method using plural separation and detection systems has been constructed.…”
