Miniature and Fieldable Mass Spectrometers: Recent Advances

“…of rotation without any cosurfactant. Moreover, unlike the previously published reports 50 – 54 . we have also presented first visual evidence (TEM image) of olive oil sitting in the micellar cavity of the surfactant, PF 127 (Fig.…”

“…This new construction provides a 20-fold decrease in cost and 30-fold decrease in size compared to previously reported TENG designs, putting it on par with the power supply equipment required for pulsed DC nESI in terms of footprint while maintaining a lower cost. − This signifcantly smaller device opens new opportunities for conducting nESI experiments in frugal academic settings, including mobile field demonstrations when powered by a small portable power station or battery. Additionally, this new portability lends well to the growing field of on-site and point of care mass spectrometry. ,− We demonstrate this new design is capable of reproducing previously reported data with high fidelity while unveiling new TENG nESI mechanisms not previously reported. We provide extensive step-by-step build instructions with the goal of democratizing TENG nESI for a wider audience in the MS field.…”

“…As can be seen in Figure , a second desorption of the stored devices revealed the presence of all pesticides spiked in the matrix. These results are certainly encouraging, because they pave the way for the implementation of SPME-TM for rapid on-site screening by means of portable instrumentation, , with the possibility of subsequent confirmation of results via benchtop instruments …”
