Zusammenfassung:The invention relates to a quick determination method of organic solvents in a pesticide preparation, and in particular relates to a quick simultaneous determination method of the content of 39 organic solvents comprising methanol, benzene, toluene, ethylbenzene, xylene, naphthalene and the like in the pesticide preparation by use of gas chromatography-mass spectrometry. The quick simultaneous determination method of the content of the 39 organic solvents comprising methanol, benzene, toluene, ethylbenzene, xylene, naphthalene and the like in the pesticide preparation by use of GC-MS is as follows: a sample is diluted with chromatographically pure acetone, and then directly injected, AgilentVF-1701 MS (60m * 0.25mm * 0.25 mu m) capillary chromatographic column is used for separation, and external standard method is used. The average recovery rate of standard addition is 92.2%-108.5%, the relative standard deviation (RSD) is ranged from 0.43% to 3.40%, the detection limit is 0.4mg / kg-18.7mg / kg, the quantit
