WebAboutTranscript. In the analytical technique of mass spectrometry, atoms or molecules are ionized using a high-energy electron beam and then separated based on their mass-to-charge ratios (m/z). The results are presented as a mass spectrum, which shows the relative abundances of the ions on the y-axis and their m/z ratios on the x-axis. WebA mass spectrum of each is shown at the top. The Kendrick mass defect plot on the bottom separates compounds by functional group (y-axis) and molecular weight (x-axis). The size of the dot indicates compound abundance, and color indicates the elemental composition. Many sulfur-, nitrogen-, and oxygen-containing compounds are visible.
