Abstract:
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.

Claim (Index 18):
A method for acquiring mass spectral data, the method comprising:\n producing an electron beam in an axial electron ionization (EI) source at a first electron energy, and focusing the electron beam along a source axis of the EI source by applying a magnetic field; introducing a first sample into the EI source; irradiating the first sample with the electron beam at the first electron energy to produce first analyte ions as an ion beam coaxial with the electron beam along the source axis; transmitting the first analyte ions into a mass analyzer via a lens assembly of the EI source to generate a first mass spectrum; adjusting the electron energy to a second electron energy different from the first electron energy; introducing a second sample into the EI source; irradiating the second sample with the electron beam at the second electron energy to produce second analyte ions as an ion beam coaxial with the electron beam along the source axis; transmitting the second analyte ions into the mass analyzer via the lens assembly to generate a second mass spectrum; and reflecting at least some ions created in the lens assembly.
