Multi-class multi-residue analysis of pesticides in edible oils by gas chromatography-tandem mass spectrometry using liquid-liquid extraction and enhanced matrix removal lipid cartridge cleanup.

•A two-step LLE is proposed to improve non-polar analyte extraction recovery.•EMR-Lipid cartridges provide pass-through cleanup for samples.•Method is validated for multiclass multiresidue pesticides testing in edible oils.•Improved GC–MS/MS method robustness is demonstrated.
