“…The instrumental setup of EESI has been documented in the literature. 7,[14][15][16][17][18][19][20] As demonstrated, it is easy to implement EESI in various commercially available mass spectrometers, even without modication of any hardware. 7 During EESI analysis, neutral samples are continuously introduced to intersect the ESI plume created by electrospraying solvents without a complex matrix, such that the neutral analytes are charged by the extractive ionization process under ambient conditions.…”

A rapid method based on extractive electrospray ionization mass spectrometry (EESI-MS) has been developed for quantitative detection of trace radioactive molecular iodine-129 ( 129 I 2 ) in negative ion detection mode in ambient air. For actual air samples, gaseous 129 I 2 was completely converted into iodine-129 ions ( 129 I À ) by an excess of Na 2 SO 3 solution. By adding excess amounts of 127 I 2 into the solution, the 129 I À ions formed triiodide ion complexes (i.e. 129+127*2 I 3 À ) which were subjected to tandem mass spectrometry experiments to exclude false positives. Quantification of iodine-129 was achieved by quantitatively measuring the characteristic fragment (i.e., 129 I À ) of the triiodide ion complexes. The calibration curve showed a good linearity within an relatively wide concentration range of 0.01-1000 ppb (R 2 ¼ 0.991), a limit of detection (LOD) of 4.5 ppt and a relative standard deviation (RSD) of 4.0-13.1% (n ¼ 5). The spiking recovery of this method was found to be 82.6-110.5%. The method had also been successfully applied to detecting the trace amount of gaseous 129 I 2 released in a simulated nuclear leakage accident, showing a satisfactory result for the tested gaseous samples. The experimental data demonstrated that EESI-MS was a useful tool for quantitative measurement of radioactive iodine in cases such as nuclear leakage, nuclear explosions and related scenarios.

“…Sample preparation is usually achieved through multi-step, laborious and time-consuming processes, which also require laboratories procedures such as solvent extraction, dilution, reagent mixing, sonication, heating, centrifugation, and filtration. Although these analytical processes work well for analysis of large numbers of samples at centralized locations, it is also highly desirable to develop fast and easy-to-use methods for on-site screening, especially for situations when rapid decision making is required by inspectors in the field [40, 41]. …”

Significantly simplified work flows were developed for rapid analysis of various types of cosmetic and foodstuff samples by employing a miniature mass spectrometry system and ambient ionization methods. A desktop Mini 12 ion trap mass spectrometer was coupled with paper spray ionization, extraction spray ionization and slug-flow microextraction for direct analysis of Sudan Reds, parabens, antibiotics, steroids, bisphenol and plasticizer from raw samples with complex matrices. Limits of detection as low as 5 μg/kg were obtained for target analytes. On-line derivatization was also implemented for analysis of steroid in cosmetics. The developed methods provide potential analytical possibility for outside-the-lab screening of cosmetics and foodstuff products for the presence of illegal substances.
