  • A compact high-resolution X-ray ion mobility spectrometer 
    Reinecke, Tobias; Kirk, Ansgar T.; Heptner, Andre; Niebuhr, D.; Böttger, S.; Zimmermann, Stefan (College Park, MA : American Institute of Physics (AIP), 2016)
    For the ionization of gaseous samples, most ion mobility spectrometers employ radioactive ionization sources, e.g., containing 63Ni or 3H. Besides legal restrictions, radioactive materials have the disadvantage of a constant ...
  • Shutterless ion mobility spectrometer with fast pulsed electron source 
    Bunert, Erik; Heptner, Andre; Reinecke, T.; Kirk, Ansgar T.; Zimmermann, Stefan (College Park, MA : American Institute of Physics (AIP), 2017)
    Ion mobility spectrometers (IMS) are devices for fast and very sensitive trace gas analysis. The measuring principle is based on an initial ionization process of the target analyte. Most IMS employ radioactive electron ...
