Triple quadrupole mass spectrometer

  "id": "MLC-T-CHM-012291",
  "term": "Triple quadrupole mass spectrometer",
  "field": "Chemistry",
  "definition": "An instrument that couples two transmission quadrupole mass spectrometers in series, separated by a radio frequency (RF) only quadrupole acting as a collision cell. The first quadrupole (Q1) selects a precursor ion, which is fragmented in the collision cell (q2), and the resulting product ions are then separated by the third quadrupole (Q3). This tandem-in-space configuration is distinct from a tandem-in-time instrument like an ion trap.",
