quadrupole mass analyzer

Arrangements of four electrostatic rods (Quad) in which ions with a desired quotient mass/ charge are made to describe a stable path under the effect of a static and a high- frequency electric quadrupole field applied to the rods, and are then detected. Ions with a different mass/ charge are separated from the detected ions because of their unstable paths deflecting them from the axis towards the detector.

The term "quadrupole mass analyzer" was found in the following pages:
