This work describes a rapid and sensitive ion mobility spectrometry method for the determination of aflatoxins G1 and G2 (AFG1 and AFG2 ). The effective instrumental parameters were investigated and optimized. After optimizing, the calibration curves for AFG1 and AFG2 were linear in the range of 1 to 300 ng. Relative standard deviation was 8% and limit of detection was 0.5 ng. The capability of the proposed method was evaluated for the determination of AFG in spiked pistachio nut as a real sample that satisfactory results were obtained.
