Definition of mass spectrum in English:

mass spectrum


  • A distribution of ions shown by the use of a mass spectrograph or mass spectrometer.

    • ‘Their authenticity was confirmed by UV, electrospray mass spectra and high-field proton NMR spectroscopy.’
    • ‘The structures of these derivatives were characterized with proton nuclear magnetic resonance, infrared and mass spectra.’
    • ‘The resulting fragment ions were subjected to mass analysis to produce a tandem mass spectrum.’
    • ‘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.’
    • ‘A mass spectrum of gramicidin in methanol shows three sets of peaks, corresponding to the different gramicidin species that are present in the sample.’
