“…The method is based on the hydrolysis of psilocybin to psilocin and a selective extraction of psilocin from the extracts by 1-chlorobutane. Recently Keller et al (1999aKeller et al ( , 1999bKeller et al ( , 2006 used ion mobility spectrometry to identify psilocybin and psilocin in finely cut samples of Psilocybe subcubensis. The method is highly sensitive but not entirely specific since psilocybin is thermally degraded to psilocin during analysis.…”

“…IMS can be used in post-explosion detection of traces; for example, detection of PETN has been made from a detonating fuse and from a tissue sample taken from the thorax region during autopsy (Keller et al, 2006). IMS has also been used to detect explosive residues on the surfaces of metal scrap (Jung et al, 2004), and to detect taggants in explosives (Ewing & Miller, 2001).…”

In recent years, explosive materials have been widely employed for various military applications and civilian conflicts; their use for hostile purposes has increased considerably. The detection of different kind of explosive agents has become crucially important for protection of human lives, infrastructures, and properties. Moreover, both the environmental aspects such as the risk of soil and water contamination and health risks related to the release of explosive particles need to be taken into account. For these reasons, there is a growing need to develop analyzing methods which are faster and more sensitive for detecting explosives. The detection techniques of the explosive materials should ideally serve fast real-time analysis in high accuracy and resolution from a minimal quantity of explosive without involving complicated sample preparation. The performance of the in-field analysis of extremely hazardous material has to be user-friendly and safe for operators. The two closely related ion spectrometric methods used in explosive analyses include mass spectrometry (MS) and ion mobility spectrometry (IMS). The four requirements-speed, selectivity, sensitivity, and sampling-are fulfilled with both of these methods.

“…The number of ions reach to the detector is considered as a measure of the analytes concentration. IMS has applied for the rapid and sensitive detection of trace amounts of a broad range of compounds [17][18][19][20] .…”

This work describes a rapid and sensitive ion mobility spectrometry method for the determination of aflatoxins G 1 and G 2 (AFG 1 and AFG 2 ). The effective instrumental parameters were investigated and optimized. After optimizing, the calibration curves for AFG 1 and AFG 2 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.Key words: Aflatoxin G (AFG), Aflatoxin B (AFB), Ion mobility spectrometry (IMS), Pistachio nut.Some reports indicate natural contamination with AFB and AFG mainly in countries with warm and humid climate [6][7][8] .
