In the ever-evolving field of mass spectrometry, a void exists in the availability of field-portable devices that can provide in situ analysis with suitable performance characteristics. In this work, a miniaturized coaxial ion trap mass analyzer is developed, simulated, and characterized. This work, funded by the National Science Foundation, is carried out in conjunction with Brigham Young University. The device in discussion is novel in that it utilizes a rectilinear ion guide (RIG), a simplified toroidal ion trap (STorIT), and a cylindrical ion trap (CIT) in the device’s center. The inclusion of the STorIT provides a high trapping capacity, and the ability to repeatedly mass-selectively eject ions from the STorIT into the CIT leads to increased analytical efficiency. Topics of interest in this paper include the design and fabrication of the device, as well as simulation results and future work to characterize its performance.
