Webmass spectrum is relative intensity.Therefore, the height of each of the peaks will correspond to the relative abundance of each isotope in the sample. As an example, examine Figure 1.This is a mass spectrum of a natural sample of atomic carbon. 12 C, with a natural abundance of 98.89%, naturally has a very high peak. 13 WebA mass spectrometer ionizes atoms and molecules with a high-energy electron beam and then deflects the ions through a magnetic field based on their mass-to-charge ratios ( m/z m/z ). The mass spectrum of a sample shows the relative abundances of the ions on the y-axis and their m/z m/z ratios on the x-axis. If z = 1 z = 1
