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 20):
An ion source, comprising:\n an ionization chamber comprising a first end and a second end, and having a length along a source axis from the first end to the second end; an electron source positioned at the first end and configured to accelerate an electron beam through the ionization chamber along the source axis; a lens assembly positioned at the second end, the lens assembly configured to transmit analyte ions created in the ionization chamber out from the lens assembly along the source axis, and to reflect at least some ions created in the lens assembly; and a controller communicating with the electron source and the lens assembly, the controller configured to control an operation comprising: producing the electron beam at a first electron energy; introducing a sample comprising an analyte of interest into the EI source; irradiating the sample with the electron beam at the first electron energy to produce first analyte ions from the analyte of interest as an ion beam coaxial with the electron beam along the source axis; transmitting the first analyte ions into a mass analyzer via the lens assembly to generate a first mass spectrum correlated to the first electron energy; adjusting the electron energy to a second electron energy different from the first electron energy; irradiating the sample with the electron beam at the second electron energy to produce second analyte ions from the analyte of interest as an ion beam coaxial with the electron beam along the source axis; and transmitting the second analyte ions into the mass analyzer via the lens assembly to generate a second mass spectrum correlated to the second electron energy.
