Detection of designer drugs in human hair by ion mobility spectrometry (IMS).

Forensic Science International, 1998
Since its inception in the early 1970s under the name plasma chromatography, ion mobility spectrometry (IMS) has undergone great changes. It is now utilized more and more in forensic science laboratories where it is used to detect explosives and environmental pollutants [1-4] as well as its use in detecting drugs of abuse [5-8].

Applications of ion mobility spectrometry (IMS) in the field of foodomics

Food Research International, 2013
Abstract Several new and innovative applications of ion mobility spectrometry (IMS) and related technologies in the field of foodomics have emerged in the last decade. Among these are the assessment of food freshness or the degree of spoilage of muscle food products, the determination of the level of odorants in wine responsible for the “off flavor”,

Recent progress in food flavor analysis using gas chromatography-ion mobility spectrometry (GC-IMS).

Food Chemistry, 2020
Rapid, nondestructive, high-throughput testing and screening of volatile ingredients plays an important role in food flavor analysis. Gas chromatography-ion mobility spectrometry (GC-IMS) is a powerful technique for the separation and sensitive detection of volatile organic compounds.

THE IMS PARADOX: A PERSPECTIVE ON STRUCTURAL ION MOBILITY‐MASS SPECTROMETRY

Mass Spectrometry Reviews, 2020
Studies of large proteins, protein complexes, and membrane protein complexes pose new challenges, most notably the need for increased ion mobility (IM) and mass spectrometry (MS) resolution. This review covers evolutionary developments in IM‐MS in the authors' and key collaborators' laboratories with specific focus on developments that enhance the ...

Thin Layer Chromatography-Ion Mobility Spectrometry (TLC-IMS)

Analytical Chemistry, 2014
Ion mobility spectrometry (IMS) is a fast and sensitive analytical method which operates at the atmospheric pressure. To enhance the capability of IMS for the analysis of mixtures, it is often used with preseparation techniques, such as GC or HPLC. Here, we report for the first time the coupling of the thin-layer chromatography and IMS.

Analyzing Positive Reactant Ions in High Kinetic Energy Ion Mobility Spectrometry (HiKE-IMS) by HiKE-IMS–MS

Journal of the American Society for Mass Spectrometry, 2020
In contrast to classical ion mobility spectrometers (IMS) operating at ambient pressure, the high kinetic energy ion mobility spectrometer (HiKE-IMS) is operated at reduced pressures between 10-40 mbar. In HiKE-IMS, ions are generated in a reaction region before they are separated in a drift region.
