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] .

“…[1][2][3][4][5] Instrumental methods, which are generally used to detect nitro explosives, include gas chromatography coupled with mass spectrometry, [6][7][8] nuclear quadrupole resonance, 9 energy dispersive X-ray diffraction, 10 and ion mobility spectrometry (IMS), 11,12 but all these methods are rather expensive, and can hardly be made portable. In addition, many of these techniques require special equipment and/or need in pre-concentrating procedures.…”

New D-π-A-π-D type dyes based on compounds of the pyrimidine family, bearing thiophene linkers, have been designed, synthesized and characterized. The fluorescence behavior of these fluorophores have been evaluated for fifteen nitro compounds. The detection limits for these fluorophores in relation to nitro explosives in acetonitrile solution proved to be in the range from 10 -1 to 10 -6 mol/L. The sensor prototypes for handheld sniffer «Nitroscan» (Plant «Promautomatika», Ekaterinburg, Russia), based on these fluorophores, have been fabricated and used, as illustrated by reversible and sensitive fast detection of nitrobenzene in vapor phase concentrations up to 0.06 ppm.

“…CD is nonradioactive which is capable of producing a current one order of magnitude higher than 63 Ni and it has successfully been used to detect many compounds. 33,34 This paper reports a new method developed for the direct determination of MEL in milk, dairy products and egg yolk sample using CD-IMS combined with DLLME. In this work, for the first time a combination of DLLME and CD-IMS (DLLME-CD-IMS) was used for the determination of MEL in food samples without other pre-separation treatment.…”

In this work, for the first time, a highly sensitive method based on dispersive liquid-liquid microextraction coupled with positive corona discharge ion mobility spectrometry as a fast and inexpensive technique has been evaluated for the direct determination of melamine. The effective parameters influencing the microextraction efficiency, such as pH, the properties of extraction and dispersion solvent were investigated. Under the optimum conditions, analytical parameters such as linearity, precision and limit of detection were evaluated. The calibration graph of melamine determination using the proposed method has two regions of linearity from 0.5 to 70 ng mL -1 and 70 to 1500 ng mL -1 , the limit of detection and limit of quantification are 0.25 and 0.5 ng mL -1 , respectively, and the relative standard deviation was less than 3% for all experiments. The proposed method was successfully applied for the determination of melamine in the milk, dairy products and egg yolk.
