Abstract:
A scaled down version of a toroidal radio frequency (RF) ion trap mass analyzer operating with RF trapping voltages on the order of 1 kVp-p yet despite the reduced dimensions, retains roughly the same ion trapping volume as conventional 3D quadrupole ion traps, wherein the curved geometry enables construction of a compact mass analyzer and easy interface with conventional electron multipliers.
