ion trap analyzer
An ion trap analyzer consists of two end caps and a ring electrode assembled into a compact device that serves as a mass analyzer. The three-dimensional rotationally symmetric quadrupole field stores ions (externally generated) at its center. An additional electrical signal is then applied to mass-selectively eject ions to an external detector.
