Opioid Cutting Agents for Use as Internal Standards in Ion Mobility Spectrometry (IMS)
Talanta, 2023Opioids have become a serious public health concern over the last decade. These compounds are commonly found mixed, or cut, with safer compounds to make the opioids appear unadulterated while also enhancing the psychoactive effect on the user. Commercial benchtop and handheld IMS devices are capable of detection but published reduced ion mobility (K0 ...

THE IMS PARADOX: A PERSPECTIVE ON STRUCTURAL ION MOBILITY‐MASS SPECTROMETRY
Mass Spectrometry Reviews, 2020Studies 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, 2014Ion 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.
