  "id": "MLC-T-CHM-004461",
  "term": "Fixed precursor ion scan",
  "field": "Chemistry",
  "definition": "A mass spectrometry scanning mode where the first mass analyzer is set to transmit a specific, fixed precursor ion, while the second mass analyzer scans to detect all product ions resulting from its fragmentation. This technique is used to obtain the full product ion spectrum of a chosen precursor. It provides detailed structural information about a particular ion.",
