Abstract:
A mass spectrometer system includes an ion source and a controller. The ion source includes a body 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 for accelerating an electron beam through the ionization chamber along the source axis. The controller is configured to operate the ion source in a high robustness mode by setting a second lens voltage and a filament voltage to minimize electron reflection back along the source axis towards the electron source; and operate the ion source in a high sensitivity mode by setting second lens voltage and a filament voltage to cause electron reflection back along the source axis towards the electron source.

Claim (Index 1):
A mass spectrometer system comprising:\n an ion source comprising:\n a body comprising an ionization chamber at a first end, a sample inlet into the ionization chamber, and a post ionization volume at a second end, the body having a length along a source axis from the first end to the second end; \n an electron source positioned at the first end, the electron source including a thermionic filament and a repeller, and the electron source configured for accelerating an electron beam through the ionization chamber along the source axis and repelling ions produced in the ionization volume away from the electron source; \n a first lens element positioned adjacent to the post ionization volume at the second end; and \n a second lens element positioned adjacent to the first lens element; and \n a controller configured to:\n operate the ion source in a high robustness mode by setting a second lens voltage and a filament voltage to minimize electron reflection back along the source axis towards the electron source; and \n operate the ion source in a high sensitivity mode by setting second lens voltage and a filament voltage to cause electron reflection back along the source axis towards the electron source.
