Definition of mass spectrum in English: mass spectrumnoun A distribution of ions shown by the use of a mass spectrograph or mass spectrometer. Example sentencesExamples - This analysis method helps find the composition of a physical sample by generating a mass spectrum that represents the masses of the sample's components.
- The resulting fragment ions were subjected to mass analysis to produce a tandem mass spectrum.
- A mass spectrum of gramicidin in methanol shows three sets of peaks, corresponding to the different gramicidin species that are present in the sample.
- The structures of these derivatives were characterized with proton nuclear magnetic resonance, infrared and mass spectra.
- Their authenticity was confirmed by UV, electrospray mass spectra and high-field proton NMR spectroscopy.
