  "term": "Mathieu stability diagram",
  "field": "Chemistry",
  "definition": "A graphical representation that illustrates the regions of stable ion trajectories within the parameter space of a quadrupole mass filter or ion trap. This diagram plots the stability parameters 'a' and 'q', which are functions of the applied radiofrequency and DC voltages, and the ion's mass-to-charge ratio. Ions whose 'a' and 'q' values fall within the stable region are trapped or transmitted.",
