Özet
This study outlines a sensitive analytical methodology for the determination of dipropetryn at trace levels in corn flour samples. In the scope of this study, spraying-based liquid phase microextraction (SB-LPME) was performed to preconcentrate trace levels of dipropetryn by means of a lab-made spraying apparatus. The analytical method performance of the optimized SB-LPME-GC-MS method was examined, and the limit of detection (LOD), limit of quantitation (LOQ) and linear range were figured out to be 0.39 µg kg−1, 1.31 µg kg−1 and 1.11–102.5 µg kg−1, respectively. The presented method was applied to corn flour samples spiked to five different concentrations (approximately 2.5–50 µg kg−1). Percent recovery results between 91.0% and 121.4% verified the accuracy and feasibility of the SB-LPME-GC-MS method. There is no study regarding the quantitation of dipropetryn at trace levels in corn flour samples by the SB-LPME-GC-MS method. The environmental friendliness of the developed SB-LPME-GC-MS method was confirmed by the Eco-Scale analytical tool.
