  • Patent number: 9048080
    Abstract: An accumulating ion source for a mass spectrometer that includes a sample injector (328) introducing sample vapors into an ionization space (115) and an electron emitter (102) emitting a continuous electron beam (104) into the ionization space (115) to generate analyte ions. The accumulating ion source further includes first and second electrodes (108a, 108b) arranged spaced apart in the ionization space (115) for accumulating analyte ions substantially therebetween. The first and second electrodes (108a, 108b) receive periodic extraction energy potentials to accelerate packets of analyte ions from the ionization space (115) along a first axis. An orthogonal accelerator (140) receives the packets of analyte ions along the first axis and periodically accelerates the packets of analyte ions along a second axis substantially orthogonal to the first axis.
