Performances of multiresidue analysis of one hundred of pesticides and contaminants, using GC-Q-Orbitrap method in full scan mode were compared to those obtained with GC-triple-quadrupole method in multiple reaction monitoring mode. In terms of sensitivity, 86% of molecules exhibited lower limit of detection values using GC-Q-Orbitrap than using GC-triple-quadrupole. For the GC-Q-Orbitrap method, more than 85% of the pesticides and contaminants showed good recovery [70-120%] in wheat samples, with relative standard deviation values < 20%.

- * The study demonstrated that GC×GC-EI-MS significantly improved peak separation compared to traditional GC-EI-MS, although the Orbitrap mass analyzer had limitations in data acquisition rate, which could affect the resolution of narrow chromatographic peaks.
- * The analysis of a cellulose bio-oil sample using GC×GC-MS resulted in a well-resolved chromatogram that allowed for the identification of various molecules based on their EI mass spectra, showcasing the technique's effectiveness in bio-oil analysis.
