Simultaneous determination of 45 pesticides in fruit and vegetable using an improved QuEChERS method and on-line gel permeation chromatography–gas chromatography/mass spectrometer

► We improve efficiency of QuEChERS and method automation using online GPC–GC/MS. ► Modified salting-out will improve recovery of pesticides with high water solubility. ► GPC will greatly improve peak shape of pesticides and method accuracy and precision. ► 68–118% of recoveries and
