Penning ion trap
ASMS TERMS AND DEFINITIONS POSTER ENTRY
An ion trap that confines ions by placing them in a static magnetic field. Inside the field, the ions are subject to the Lorentz force which causes ions of a particular m/z to cyclotron at a specific frequency (cyclotron frequency).

-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.
