Evaluating the variation of ion energy under different parameter settings in traveling wave ion mobility mass spectrometry
International Journal for Ion Mobility Spectrometry - Tập 21 - Trang 81-86 - 2018
Joseph N. Mwangi, Daniel A. Todd, Norman H. L. Chiu
Ion mobility mass spectrometry (IM-MS) can be used to differentiate and identify isobaric ions. To improve IM-MS resolution, the second generation of traveling wave ion mobility (TWIM) technology was launched. There were reports showing ions were heated up by TWIM. With higher ion energy, it could alter the conformation of larger ions or MS/MS experiments. To monitor the energy exchange relating t...... hiện toàn bộ

Which parameters influence the quantitative determination of halogenated substances? A summary of systematic investigations
International Journal for Ion Mobility Spectrometry - Tập 18 - Trang 33-39 - 2015
Thomas Mayer, Helko Borsdorf
In recent years, we have intensively studied the ion chemistry of halogenated substances in ion mobility spectrometry (IMS). During atmospheric pressure chemical ionization (APCI) processes, dissociative electron transfer reactions between reactant ions and halogenated molecules occur and (H2O)nX− product ions are formed, which appear as distinct product ion peak in negative ion mobility spectra. ...... hiện toàn bộ
Detection of volatile organic compounds from wood-based panels by gas chromatography-field asymmetric ion mobility spectrometry (GC-FAIMS)

High resolution electrospray ionization ion mobility spectrometry
International Journal for Ion Mobility Spectrometry - Tập 12 - Trang 33-37 - 2009
Clinton A. Krueger, Christopher K. Hilton, Mark Osgood, Jianglin Wu, Ching Wu
Current commercially available ion mobility spectrometers are intended for the analysis of chemicals in the gas phase. Sample introduction methods, such as direct air sampling, a GC injector or a thermal desorber, are commonly an integral part of these instruments. This paper describes an electrospray ionization ion mobility spectrometer system that allows direct introduction samples in solution p...... hiện toàn bộ
Zero-field mobilities in helium: highly accurate values for use in ion mobility spectrometry
International Journal for Ion Mobility Spectrometry - Tập 15 - Trang 21-29 - 2011
Larry A. Viehland
The zero-field mobilities of 46 atomic ions in helium are calculated as functions of the gas temperature in an ion mobility spectrometer. The calculations are based on highly accurate, ab initio potential energy curves obtained in the last few years. In general, they start from a small value at low temperature, rise steadily to a maximum at some specific temperature, T ...... hiện toàn bộ
Determination of formaldehyde release from wood-based panels using SPME-GC-FAIMS
International Journal for Ion Mobility Spectrometry - Tập 17 - Trang 55-67 - 2014
Sarah Himmel, Carsten Mai, Achim Schumann, Jörg Hasener, Vera Steckel, Christoph Lenth
Several standardized methods exist to determine formaldehyde (HCHO) release from wood-based panels (WBPs). These methods were developed decades ago to be used in manufacturers laboratories to provide a mean of production control. They are robust and take several hours to yield results. Modern WBP panel production, however, is a continuous process. Therefore the established methods are too time-con...... hiện toàn bộ
A novel ion detector aiming at the homogeneous of drift gas
International Journal for Ion Mobility Spectrometry - Tập 20 - Trang 111-117 - 2017
Peihe Jiang, Zhiquan Zhou, Zhanfeng Zhao
In standalone ion mobility spectrometry (IMS) instruments, the effect of drift gas turbulence reduces the sensitivity and resolution of the instrument. A traditional ion detector constructed with a Faraday plate and used to detect ions in an IMS is positioned at the end of the drift region. Drift gas flowing through this detector may introduce turbulence near the detector, possibly affecting the s...... hiện toàn bộ
Ion mobility spectra of cyclic and aliphatic hydrocarbons with different substituents
International Journal for Ion Mobility Spectrometry - Tập 12 - Trang 39-46 - 2009
Helko Borsdorf, Kristian Neitsch
We investigated the influence of structural differences on the ionization pathways and drift behavior in ion mobility spectrometry for cyclic and aliphatic hydrocarbons with different functional groups. The sets of cyclic and aliphatic compounds had an identical mass or a mass difference of 2 Da. Therefore, mass effects can be neglected during the investigation of these compounds. Depending on the...... hiện toàn bộ
