    A novel hybrid mass spectrometer (1989)
    New York, NY : Wiley-Blackwell
    Rapid Communications in Mass Spectrometry 3 (1989), S. 62-66 
    Details
    ISSN: 0951-4198
    Keywords: Chemistry ; Analytical Chemistry and Spectroscopy
    Source: Wiley InterScience Backfile Collection 1832-2000
    Topics: Physics
    Notes: A new hybrid mass spectrometer of BEQiQu geometry (B, magnetic sector; E, Electric sector; Qi, quistor; Qu, quadrupole mass filter) is described. The high resolution stage (BE) is coupled to a quistor via a series of deceleration lenses, and this is followed by a mass-analysing quadrupole. This configuration enables the storing of ions, investigation of their gas-phase chemistry and the subsequent identification of the resulting fragment or product ions.

    A deceleration lens system for hybrid mass spectrometers (1989)
    New York, NY : Wiley-Blackwell
    Rapid Communications in Mass Spectrometry 3 (1989), S. 417-419

    Topics: Physics
    Notes: A simple and efficient deceleration system for the coupling of magnetic and electric sector instruments to quadrupole analyzers is described. The trasnsmission efficiency of the system appears to be at least 80% or better as the ions are decelerated from 3 ke V to 30 eV (a deceleration factor of 1:100). No mass discrimination was observed in the range up to mass 1000.
