Research Interests:
mass spectrometry
Research:
Continuing technological developments combine to permit the design and implementation of new approaches to chemical analysis. The unifying theme of our research program is development and demonstration of new analytical methods taking advantage of these opportunities for organic chemical analysis in the broadest sense. Applications of the new techniques range from synthetic polymer characterization to bioanalytical to environmental problems.
A major research interest involves development of Fourier transform mass spectrometry (FTMS) as a rapid, specific, and sensitive analytical tool, especially for high mass analysis. Recent research emphasizes the general areas of laser desorption and matrix-assisted laser desorption, ultimately aimed at applications involving analysis of non-volatile and/or high mass compounds with masses as large as 50,000 or more. This research is also devoted to developing fundamental understanding of the processes involved and employs a variety of lasers with wavelengths from the ultraviolet through the infrared. A major project currently underway is the construction of an aerosol Fourier transform mass spectrometer, which will make possible analysis of single size-selected particles. The new instrument, that employs a 3 Tesla Oxford magnet, will be applied to both environmental and bioanalytical applications, including the analysis of single bacteria. An additional 3 Tesla FTMS and a 7 Tesla FTMS equipped with an IonSpec Omega 2001 Data Station are available for other laser desorption FTMS studies. An external source 9.4 Tesla FTMS equipped for both electrospray and MALDI is being augmented by a second 9.4 Tesla system similarly equipped and is being used to study whole cell analysis of bacteria. Also, being installed are a TOF-TOF instrument and a Q-TOF ESI system.Both heuristic and spectral database approaches to data interpretation are being investigated.
