Abstract
An orbitrap may include elongated inner and outer electrodes, wherein the inner and outer electrodes each define two axially spaced apart electrode halves with a central transverse plane extending through the electrodes also passing between both sets of electrode halves, a cavity defined radially about and axially along the inner electrode between the two inner electrode halves and the two outer electrode halves, means for establishing an electric field configured to trap an ion in the cavity and to cause the trapped ion to rotate about, and oscillate axially along, the inner electrode, wherein the rotating and oscillating ion induces charges on the inner and outer electrode halves, and charge detection circuitry configured to detect the charges induced on the inner and on outer electrode halves, and to combine the detected charges for each oscillation to produce a measured ion charge signal.
