Mass spectrometer focusing system

  "id": "MLC-T-CHM-006996",
  "term": "Mass spectrometer focusing system",
  "field": "Chemistry",
  "definition": "The assembly of a mass spectrometer that separates ions by their mass-to-charge ratio and brings each group to a focus at the detector, for example a magnetic sector, an electric sector, or the two combined in a double-focusing design. Lenses placed between the ion source and this assembly only shape and accelerate the beam and do not sort ions by mass.",
