  "id": "MLC-T-CHM-004463",
  "term": "Fixed product ion scan",
  "field": "Chemistry",
  "definition": "A mass spectrometry scanning mode where the second mass analyzer is set to detect a specific, fixed product ion, while the first mass analyzer scans to identify all precursor ions that fragment to produce this particular product. This method is useful for identifying compounds that share a common structural motif. It is also known as a parent ion scan.",
