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

The effects of cation adduction upon the conformation of three-helix bundle protein domains
International Journal for Ion Mobility Spectrometry - Tập 16 - Trang 19-27 - 2012
Kleitos Sokratous, Robert Layfield, Neil J. Oldham
The ubiquitin-binding, three-helix bundle domains of the proteins ubiquilin 1 (UQ1) and hHR23A both exhibited remarkably high, but discrete, ammonium ion adduction when electrosprayed from aqueous ammonium acetate. The degree of adduction was highly charge state dependent with, unusually, the lowest charge states (+3 for UQ1 and +4 for hHR23A) showing almost no adducts and the highest charge state...... hiện toàn bộ
Biogenic amines in bread as indicators of spoilage
International Journal for Ion Mobility Spectrometry - Tập 17 - Trang 125-129 - 2014
Gabi Cohen, Mordi Laloush, Zeev Karpas
Elevated levels of biogenic amines (trimethylamine, putrescine and cadaverine), measured by ion mobility spectrometry (IMS) were found in a sample of “dark rye” bread that had a pungent odor but not in other bread samples. The odorless breads included three types of rye bread, whole wheat, pita bread and a baguette. Sample preparation was simple and consisted of extraction of the biogenic amines i...... 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
