Study Notes

Mass Spectrometry (MS) Analysis

  • MS analysis provides information about molecular weight of a compound
  • It determines the number of specific elements in a compound based on isotope peaks
  • High-resolution MS analysis allows for the determination of molecular formula
  • MS analysis yields reproducible fragment patterns, which are useful for: • Identifying functional groups • Determining arrangement of components • Confirming compound identity
