Penning ion trap
IUPAC RECOMMENDATIONS 2013
Ion trapping device using a static magnetic field and a static electric potential well. The magnetic field confines the ion motion to circular orbits around the magnetic force line direction, which aligns with the direction of the trap axis, whereas the electric potential well confines the ion motion axially. Note: This device is used for the mass analyzer of Fourier transform-ion cyclotron resonance-mass spectrometers.

-A type of mass analyzer in which ions are confined in space by means of a three dimensional, rotationally symmetric quadrupolar electric field.  Sorting of ions is performed by changing the field conditions appropriately to destabilize an ion of a particular m/z.  The destabilized ion is then detected when it exits the trap and strikes a collection device, e.g. an electron multiplier or conversion dynode.
