Influence of injection solvent and serial dilution on matrix effect in GC–MS/MS multiresidue pesticide analysis: a factorial study across seven herbal matrices

Scientific Reports
Matrix effects (MEs) remain a major challenge in gas chromatography–tandem mass spectrometry (GC–MS/MS) analysis of pesticide residues, often leading to inaccurate quantification and reduced method robustness.
