Determination of 10 strobilurin fungicide residues in fruit by GC/MS/MS

  • A method for the determination of 10 kinds of strobilurin fungicides residues in fruits by gas chromatography-mass spectrometry with Shimadzu GC/MS-TQ8050 NX triple quadrupole was established. Fruit samples were extracted simply by acetonitrile, purified by dispersed solid phase extraction reagent and analyzed by GC/MS/MS, which greatly reduced the sample pretreatment process. The linearity of 10 kinds of Strobilurin fungicides residues was good in the range of 0.5-200 μg·L-1, and the correlation coefficients were above 0.998. The standard solution of 5.0 μg·L-1 was injected continuously for 6 needles, and the peak area RSD% was less than 8%. The recoveries of actual samples were 93.5%-104.3%. The method is rapid, simple and sensitive, and fully meets the requirements of food safety analysis for the detection of Strobilurin fungicides residues.

Abstract: A method for the determination of 10 kinds of strobilurin fungicides residues in fruits by gas chromatography-mass spectrometry with Shimadzu GC/MS-TQ8050 NX triple quadrupole was established. Fruit samples were extracted simply by acetonitrile, purified by dispersed solid phase extraction reagent and analyzed by GC/MS/MS, which greatly reduced the sample pretreatment process. The linearity of 10 kinds of Strobilurin fungicides residues was good in the range of 0.5-200 μg·L-1, and the correlation coefficients were above 0.998. The standard solution of 5.0 μg·L-1 was injected continuously for 6 needles, and the peak area RSD% was less than 8%. The recoveries of actual samples were 93.5%-104.3%. The method is rapid, simple and sensitive, and fully meets the requirements of food safety analysis for the detection of Strobilurin fungicides residues.
