Analysis of Matrix Effects of 36 Pesticide Residue in Vegetables by Ultra High Performance Liquid Chromatography-tandem Mass Spectrometry
This article uses ultra-high performance liquid chromatography-tandem mass spectrometry to study the influence of matrix effects on the detection results of 36 pesticide residues in four vegetables.The results show that the pesticide concentrations are 0.05,0.1,0.2 μg·mL-1,most pesticides in the four vegetables exhibit weak matrix effects,while a few pesticides exhibit strong matrix effects.Therefore,among the 36 pesticides,for vegetables with weak matrix effects,reagent standards can be directly used for quantitative analysis;For vegetables with strong matrix effects,it is recommended to use matrix matching standard solutions for quantitative correction.
