Abstract :In this study, a gas chromatography-mass spectrometry (GC-MS) method was developed for the detection of prosulfocarb in potato flour matrix. GC-MS parameters were elaborately evaluated to achieve well-separated analyte signal with high signal to noise ratio. Under the optimum instrumental conditions, the limits of detection and quantification (LOD and LOQ) were found as 0.54 mg/kg and 1.80 mg/kg, respectively, which facilitates the determination of prosulfocarb at ppm levels. The established method was applied to potato flour samples spiked to six different concentration levels (2.6–101.7 mg/kg). Blank analyses were also performed for three different brand samples but prosulfocarb were found in the samples below the detection limit. Satisfactory percent recoveries between 90.9 and 105.7% with %RSD (≤3,6%) were acquired for the selected sample matrix. High recoveries obtained with the matrix matching calibration strategy proved the accuracy and applicability of the developed method while low %RSD value showed the precision of the analytical method. It is suggested that the established method can be used to detect ppb/ppt levels of the analyte after a preconcentration method was applied to the sample solutions.
