Mass spectroscopy (MS) is another technique commonly used by chemists for the identification of unknown compounds . One of the first, and still a popular MS ionization technique is electron ionization (EI-MS) , a method performed by bombarding the analyte in the gas phase with high energy electrons (~70 eV) for molecular ionization. The resulting cationic radicals are energetically unstable and break apart, resulting in smaller charged particle fragments that are specific to the analyte. Such fragmentation patterns are dependent on molecular functional groups and their arrangements with other functional groups and motifs. The abundance of fragments with a given mass to charge ratio (m/z) is recorded and reported as the mass spectrum.
