The core of Dr. Eiceman’s research program is the exploration of ion-molecule gas phase reactions at ambient pressure in order to develop predictive models of the creation of ion mobility spectra. These studies presently involve the kinetics of thermal decomposition of proton-bound cluster ions in air. Secondary interests include the advancement of instrumentation and drift tube technology for IMS and selected applications in environmental venues. Separation sciences with gas chromatography constitutes another area of interest.
