Applications of Ion Mobility Spectrometry (IMS) to the Analysis of gamma-Hydroxybutyrate and gamma-Hydroxyvalerate in Toxicological Matrices [PDF]

open access: yesJournal of Analytical Toxicology, 2006
The predator drug gamma-hydroxybutyrate (GHB) and its lactone form gamma-butyrolactone (GBL) continue to present significant analytical challenges to forensic toxicologists and chemists. The five-carbon analogue (gamma hydroxyvalerate GHV) and the corresponding lactone GVL) are emerging as substitutes for GHB, adding further complications. Ion mobility

Implementation of an Open-Source Multiplexing Ion Gate Control for High Kinetic Energy Ion Mobility Spectrometry (HiKE-IMS)

open access: yesJournal of the American Society for Mass Spectrometry, 2023
With ion mobility spectrometry increasingly used in mass spectrometry to enhance separation by increasing orthogonality, low ion throughput is a challenge for the drift-tube ion mobility experiment. The High Kinetic Energy Ion Mobility Spectrometer (HiKE-IMS) is no exception and routinely uses duty cycles of less than 0.1%. Multiplexing techniques such
