“…The identity of each peak was confirmed by cross referencing the K 0 values measured in the current study to the K 0 values obtained in nitrogen as the drift gas by other researchers . The peak patterns can be used as anion identification since they were unique and reproducible for each anion . However, mass identification of the peaks is necessary to identify these anions.…”

Pipes are the primary structural elements used for transporting fluid in various industries. The most common damage mechanism is corrosion, which occurs in pipes surface of turbine. The corrosive compounds for pipes are inorganic ion (Na + , Cl − , NH 4 + , NO 3 − , etc.) and grinding oil. For rapid and quantitative detection of inorganic ions on site, more reliable and reproducible analytical methods are demanded. A highly efficient solid-liquid sampling collection system is introduced in this work. Papering on the sample surface, inorganic cations and anions were simultaneously collected and analyzed by capillary electrophoresis with indirect ultraviolet detection. As a result, five cations (Na + , K + , NH 4 + , Ca 2+ , Mg 2+ ) and three anions (Cl − , NO 3 − , SO 4 2− ) were completely separated. The efficiency of the sampling and ability of capillary electrophoresis analysis were presented by the determination of tracelevel (mg/m 2 ) contaminants. The recoveries of cations and anions on the paper from metal surface were between 86.6 and 107.2%, and the relative standard deviations were less than 12.85%.

“…The sample molecules need to be ionized, usually through techniques involving radioactive sources, 21 corona discharge, 22 and electrospray ionization source. 23,24 The originated ions are separated under the influence of an electric field and drift gas flow, in the opposite direction of ions migration. When ions arrive at the collector, positioned at the end of the drift tube, the corresponding ion peak(s) appear in the ion mobility spectrum.…”

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%.
