摘要
Mass spectrometry is performed utilizing an electron ionization (EI) source. The EI source ionizes a sample at different electron energies, including below and above 70 eV. The EI source may be utilized for soft ionization as well as hard ionization. The value of the electron energy may be selected so as to favor the formation of molecular ions or other ions of high analytical value. The ion source may be an axial ion source.
