Understanding Mass Spectrometry
Summary
Mass spectrometry measures mass-to-charge ratios. It is a common way to check whether observed mass is consistent with an expected molecule.
Key concepts
- Ionization
- Mass-to-charge ratio
- Expected vs. observed mass
- Identity testing
Research context
On a COA, mass spectrometry is typically used to support identity, while chromatography is used to characterize purity.
Evidence type
Review. Evidence labels are navigational aids. Preclinical findings do not establish human safety or efficacy.
Limitations
Consistent mass supports, but does not on its own prove, structural identity.
