Constant neutral mass gain spectrum

{
  "id": "MLC-T-CHM-002463",
  "term": "Constant neutral mass gain spectrum",
  "field": "Chemistry",
  "definition": "A mass spectrum recorded by scanning a range of precursor ions that, upon fragmentation, form product ions by the addition of a pre-selected neutral mass. This technique involves varying the mass-to-charge ratios of both the precursor and product ion analyzers while maintaining a fixed mass difference corresponding to the neutral gain. Constant neutral mass gain analysis is a specialized scan mode used in tandem mass spectrometry to identify compounds that undergo a specific addition reaction, such as adduction, within the collision cell.",
