What is a neutral loss scan in mass spectrometry?
In tandem mass spectrometry or GC-MS/MS, neutral loss scan is a measuring mode that is used to study compounds showing a common neutral molecule loss during collision-induced dissociation (CID).
In measurements using neutral loss scan, fragments lost as neutral molecules are recorded in Da neutral loss scan values.
Some applications of mass spectrometry is in:
- identification and characterization drug metabolites
- authentication and profiling of chemical compounds
- substructure analysis of unknown components
- quantification of analytes in biological samples
In conclusion, neutral loss scan is a mode of measurement in tandem spectrometry.
