A scaled down version of a toroidal radio frequency (RF) ion trap mass analyzer operating with RF trapping voltages on the order of 1 kVyet 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.

Miniature toroidal radio frequency ion trap mass analyzer

A virtual ion trap that uses electric focusing fields instead of machined metal electrodes that normally surround the trapping volume, wherein two opposing surfaces include a plurality of uniquely designed and coated electrodes, and wherein the electrodes can be disposed on the two opposing surfaces using plating techniques that enable much higher tolerances to be met than existing machining techniques.
