On-line analysis of coffee roasting with ion mobility spectrometry–mass spectrometry (IMS–MS) [PDF]
International Journal of Mass Spectrometry, 2018 Online analysis of coffee roasting was performed using ion mobility spectrometry–mass spectrometry (IMS-MS) with corona discharge ionization. This is the first time that formation of volatile organic compounds (VOCs) during coffee roasting was monitored not only in positive but also in negative ion mode, and not only with mass spectrometry, but also ...

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.

Laserspray ionization (LSI) ion mobility spectrometry (IMS) mass spectrometry [PDF]
Journal of the American Society for Mass Spectrometry, 2010 A simple device is described for desolvation of highly charged matrix/analyte clusters produced by laser ablation leading to multiply charged ions that are analyzed by ion mobility spectrometry-mass spectrometry. Thus, for example, highly charged ions of ubiquitin and lysozyme are cleanly separated in the gas phase according to size and mass (shape and

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.
