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 ...
Measurement of exhaled volatile organic compounds from patients with chronic obstructive pulmonary disease (COPD) using closed gas loop GC-IMS and GC-APCI-MS

Allers, Maria; Langejuergen, Jens; Gaida, Arne; Holz, O.; Schuchardt, Sven; Hohlfeld, Jens M.; Zimmermann, Stefan (Bristol : IOP, 2016)

Due to its high sensitivity, compact size and low cost Ion Mobility Spectrometry (IMS) has the potential to become a point-of-care breath analyzer. Therefore, we developed a prototype of a compact, closed gas loop IMS with ...
Quantitative Detection of Benzene in Toluene- and Xylene-Rich Atmospheres Using High-Kinetic-Energy Ion Mobility Spectrometry (IMS)

Langejuergen, Jens; Allers, Maria; Oermann, Jens; Kirk, Ansgar T.; Zimmermann, Stefan (Washington D.C. : American Chemical Society, 2014)

One major drawback of ion mobility spectrometry (IMS) is the dependence of the response to a certain analyte on the concentration of water or the presence of other compounds in the sample gas. Especially for low proton ...
