Tandem mass spectrometer

  "term": "Tandem mass spectrometer",
  "field": "Chemistry",
  "definition": "An instrument that combines two or more mass analyzers in series to perform multiple stages of mass spectrometry, often denoted as MS/MS. In a typical experiment, the first analyzer selects a precursor ion from a mixture, which is then fragmented in a collision cell, and the resulting product ions are separated and detected by the second analyzer. This configuration contrasts with single-stage mass spectrometers that perform only one round of mass analysis.",
