Positive Reactant Ion Formation in High Kinetic Energy Ion Mobility Spectrometry (HiKE-IMS) [PDF]
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 of between 10 and 40 mbar and higher reduced electric field strengths of up to 120 Td.

Negative Reactant Ion Formation in High Kinetic Energy Ion Mobility Spectrometry (HiKE-IMS) [PDF]
Journal of the American Society for Mass Spectrometry, 2020 Due to the operation at background pressures between 10-40 mbar and high reduced electric field strengths of up to 120 Td, the ion–molecule reactions in High Kinetic Energy Ion Mobility Spectrometers (HiKE-IMS) differ from those in classical ambient pressure IMS.

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 ...

Detection of designer drugs in human hair by ion mobility spectrometry (IMS)
Forensic Science International, 1998Since 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].

Analysis of explosives using electrospray ionization/ion mobility spectrometry (ESI/IMS)
Talanta, 2000The analysis of explosives with ion mobility spectrometry (IMS) directly from aqueous solutions was shown for the first time using an electrospray ionization technique. The IMS was operated in the negative mode at 250 degrees C and coupled with a quadrupole mass spectrometer to identify the observed IMS peaks.

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.
