An analytical model for the optimum drift voltage of drift tube ion mobility spectrometers with respect to resolving power and detection limits

Kirk, Ansgar T.; Zimmermann, Stefan (Berlin, Heidelberg : Springer, 2015)

One of the key experimental parameters of measurements using a drift tube ion mobility spectrometer is the drift voltage applied across its length, as it governs a multitude of processes during the ion drift. While the ...
Miniaturized high-performance drift tube ion mobility spectrometer

Ahrens, André; Hitzemann, Moritz; Zimmermann, Stefan (Heidelberg : Springer Verlag, 2019)

Developing powerful hand-held drift tube ion mobility spectrometers (IMS) requires small, lightweight drift tubes with high analytical performance. In this work, we present an easy-to-manufacture, miniaturized drift tube ...
Novel ion drift tube for high-performance ion mobility spectrometers based on a composite material

Ahrens, André; Möhle, Janina; Hitzemann, Moritz; Zimmermann, Stefan (Berlin : Springer, 2020)

Ion mobility spectrometers (IMS) are able to detect pptV-level concentrations of substances in gasses and in liquids within seconds. Due to the continuous increase in analytical performance and reduction of the instrument ...
Pushing a compact 15 cm long ultra-high resolution drift tube ion mobility spectrometer with R = 250 to R = 425 using peak deconvolution

Kirk, Ansgar T.; Zimmermann, Stefan (Berlin, Heidelberg : Springer, 2015)

Recently, we have published an analytical model describing the resolution and signal-to-noise-ratio of peaks present in an ion mobility spectrum acquired by a drift tube instrument. Based on this model, we designed a ...
Simulation aided design of a low cost ion mobility spectrometer based on printed circuit boards

Bohnhorst, A.; Kirk, Ansgar T.; Zimmermann, S. (Berlin, Heidelberg : Springer, 2016)

Miniaturized low-cost drift tubes with high analytical performance are a key component for the design of powerful and mass-deployable hand-held ion mobility spectrometers. Thus, a simple model that estimates the influence ...
A universal relationship between optimum drift voltage and resolving power

Kirk, Ansgar T.; Bakes, Kai; Zimmermann, Stefan (Berlin, Heidelberg : Springer, 2017)

The drift voltage is one of the key experimental parameters of any drift tube ion mobility spectrometer. In this work, we show that a universal relationship between optimum drift voltage and the resolving power reached at ...
