  • Electron capture detector based on a non-radioactive electron source: Operating parameters vs. Analytical performance 
    Bunert, Erik; Kirk, Ansgar T.; Oermann, Jens; Zimmermann, Stefan (Göttingen : Copernicus GmbH, 2017)
    Gas chromatographs with electron capture detectors are widely used for the analysis of electron affine substances such as pesticides or chlorofluorocarbons. With detection limits in the low pptv range, electron capture ...
  • Electron Capture Detector with Non-Radioactive Electron Source 
    Bunert, Erik; Kirk, Ansgar T.; Oermann, Jens; Zimmermann, Stefan (Basel : MDPI, 2017)
    Gas chromatographs equipped with electron capture detectors (ECD) are widely used for the analysis of electron affine substances. Achieving limits of detection in the low pptv-range, electron capture detectors are the most ...
  • Fast pulsed operation of a small non-radioactive electron source with continuous emission current control 
    Cochems, Philipp; Kirk, Ansgar T.; Bunert, Erik; Runge, M.; Goncalves, P.; Zimmermann, Stefan (College Park, MA : American Institute of Physics (AIP), 2015)
    Non-radioactive electron sources are of great interest in any application requiring the emission of electrons at atmospheric pressure, as they offer better control over emission parameters than radioactive electron sources ...
  • Ion mobility spectrometer with orthogonal X-Ray source for increased sensitivity 
    Bunert, Erik; Reinecke, Tobias; Kirk, Ansgar T.; Bohnhorst, Alexander; Zimmermann, Stefan (Amsterdam : Elsevier, 2018)
    Ion mobility spectrometers (IMS) are compact devices for extremely sensitive detection of proton and electron affine volatile compounds down to low pptv concentrations within less than a second. The measuring principle ...
  • 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 ...
