This work demonstrates that:
- MSE–HS–trap is a fully automated, high-throughput method for the simultaneous detection of fumigant residues on foodstuffs.
- Large-volume preconcentration: Exploiting the trap, larger than conventional headspace volumes (up to 5 mL) can be extracted from the sample vial, increasing the amount of each analyte extracted
for detection.
- The method does not generate solvent waste and is therefore substantially greener than other technologies such as QuEChERS.
- The method is robust, quantitative and highly sensitive, and able to detect fumigants at concentrations well below regulatory limits.
- Removes complex and manual preparation steps (e.g., solvent extraction and/or derivatisation).
