“…Over the last two decades, IMS has evolved as a powerful analytical technique for the detection of trace levels of volatile and semi‐volatile organic compounds at atmospheric pressures . According to the statistical data analysis of Sorribes‐Soriano and co‐workers , from 2000 till today, “IMS” topic has an average rate of 140 published papers per year, being published, in 2016, more than 250 papers. The analytical potential of IMS is highlighted into its operational speed, cheap, sensitivity, portability, easiness to use and operation at atmospheric pressure .…”

In a previous review (Sánchez-Camargo et al., J. Sep. Sci. 40 (2017) 213-227), we discussed the application of on-line supercritical fluid extraction coupled to chromatographic techniques. This review includes an update of the most recent publications (from January 2016 till June 2018) on this topic, which employs advanced analytical techniques for extracting and identifying valuable analytes. Supercritical fluid extraction has been widely recognized as a green sample preparation technique, because it is efficient, environmentally friendly, powerful, and faster, offering the possibility of direct coupling to analytical instrumental techniques. Among those techniques, supercritical fluid chromatography has experienced an innovative progression in the last 10 years, and the most recent applications of supercritical fluid extraction are coupled to this advanced analytical tool. The general principles, both methodological and instrumental of on-line supercritical fluid extraction coupled to supercritical fluid chromatography are described here. Besides, applications of the mentioned coupling for analysing biological fluids, food, soil, and botanical samples are also presented and discussed. Finally, a brief description about the very recent on-line coupling of supercritical fluid extraction to ion mobility spectrometry is presented, as well as concluding remarks about the importance of using these coupled techniques in the near future.

In this research, an effective sample preparation method called solvent‐assisted dispersive solid‐phase extraction followed by corona discharge ion mobility spectrometry was proposed for the trace determination of organophosphorus pesticides in environmental water samples. In this method, to maximize the interaction surface between target analytes and sorbent, the sorbent was dispersed into the aqueous sample. In this technique, the sorbent was dispersed at very low levels using a solution of sorbent and disperser solvent into the aqueous sample. Then, a cloudy solution was created by dispersing the sorbent particles in aqueous solution. After the interaction of organophosphorus pesticides and benzil, the cloudy solution was centrifuged and organophosphorus pesticides in the solid phase were dissolved in ethanol. In order to obtain the best extraction efficiency, the optimization of parameters affecting this method was examined. After optimization, the results were obtained as follows: pH of solution: 7.0, sorbent: benzil, 2% w/v, disperser solvent: ethanol, 500 µL, and centrifuge: centrifuged at 6000 rpm for 2 min. The presented method showed low method detection limit (0.3 ng mL−1), excellent preconcentration factor (368–376), good linearity (>0.994), repeatability (RSD < 4.1%), and high recoveries (92–94%).

“…25 IMS has a wide range of applications in the analysis of explosives, medical drugs, pesticides, and air pollutants, due to its high speed, ruggedness, sensitivity, and ease of maintenances. 26,27 The thermal desorption injection port is commonly used to make a gas-phase sample, prior to analysis by IMS equipped with corona discharge or 63 Ni ionization sources. However, this sample introduction system cannot be used for thermally unstable materials due to decomposition of their molecules.…”

Propoxur insecticide as a thermally unstable compound (decomposed at its boiling point) could not be analyzed by traditional sample introduction systems based on the thermal desorption. In this study, an ultrasonic piezoelectric nebulizing injection port was applied for evaporating this compound prior to its determination by corona discharge ionization ion mobility spectrometry (CD-IMS). The target analyte was extracted from different water samples by using the extraction method of dispersive liquid-liquid microextraction. Methanol and trichloromethane were utilized as the disperser and extraction solvents, respectively. The effective variables included the volume of the disperser and the extraction solvents, the pH, and the centrifugation time were studied by a Fractional Factorial Design to identify the important parameter(s) and their interaction. To that end, a Central Composite Design was performed to achieve optimum levels of each effective parameter. The results showed that the optimum conditions were 78 μL of the extraction solvent, and 1.2 mL for the disperser solvent; centrifugation time was 1 min at 1010g, and finally pH 7. A detection limit of 2.1 μg L-1 , a linear range of 2.5-80 μg L-1 , and a relative standard deviation of 7% were obtained. Different water samples were analyzed by the proposed technique, and the propoxur amounts were successfully determined. The obtained results revealed satisfactory relative recovery values of between 91 and 105%.
