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 ...
Towards a hand-held, fast, and sensitive gas chromatograph-ion mobility spectrometer for detecting volatile compounds

Ahrens, André; Zimmermann, Stefan (Berlin [u.a.] : Springer, 2020)

Ion mobility spectrometers can detect gaseous compounds at atmospheric pressure in the range of parts per trillion within a second. Due to their fast response times, high sensitivity, and limited instrumental effort, they ...
