  • 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 ...
  • Investigation of ion-ion-recombination at atmospheric pressure with a pulsed electron gun 
    Heptner, Andre; Cochems, Philipp; Langejuergen, Jens; Gunzer, Frank; Zimmermann, Stefan (Cambridge : Royal Society of Chemistry, 2012)
    For future development of simple miniaturized sensors based on pulsed atmospheric pressure ionization as known from ion mobility spectrometry, we investigated the reaction kinetics of ion-ion-recombination to establish ...
  • Pulsed electron source for atmospheric pressure chemical ionization in ion mobility spectrometry 
    Bunert, Erik; Heptner, Andre; Kirk, Ansgar T.; Käbein, Oliver; Zimmermann, Stefan; Kusch, Alexander; Wurz, Marc Christopher (Piscataway, NJ : IEEE, 2017)
    Ion mobility spectrometers (IMS) are measurement devices for fast and ultra-sensitive trace gas analysis. Most IMS employ radioactive electron sources, such as 3 H or 63 Ni, to provide free electrons with high kinetic ...
  • 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 ...
