Ion Mobility Spectrometry with Laser-Produced Ions

Abstract

The purpose of this work has been to investigate laser multiphoton ionization (MPI) as an atmospheric pressure ionization source for ion mobility spectrometry (IMS). This has included a study of the potential of MPI for improving selectivity and specificity in IMS and also an investigation of the fundamentals of laser MPI under atmospheric conditions. A second focus of this work has been to extend IMS to nonvolatile molecules using a pulsed laser desorption method for volatilization. The final report contains the research findings. Keywords: Atmospheric pressure ionization, Ion mobility spectrometry, Laser multiphonon ionization, Nonvolatile molecules, Pulsed lasers, Laser ionization.
