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. This data can be used to calculate the exact masses of the atoms or mole
