Research Summary

Analytical Spectroscopy/Mass Spectrometry/Laboratory Automation

  • The latest technological advances in electronics, physics, optics, acoustics, mechanical engineering and computer science are being utilized to develop new and improved analytical spectrochemical techniques. A multifaceted but strongly interlocking program designed to elucidate fundamental phenomena occurring in systems employed for spectrochemical analysis is currently underway. Fundamental theoretical knowledge obtained in these studies is being applied toward the development of more accurate and sensitive analytical techniques.

    Over the past twenty years, focal plane array detectors have brought an amazing revolution to analytical spectroscopy, providing increased sensitivity, dynamic range, and improved background correction. New generations of these detectors are being developed and applied to a variety of spectroscopic techniques, including fluorescence, phosphorescence, Raman, and atomic emission analysis. Raman spectroscopy utilizing advanced instrumental concepts, including far-UV laser excitation, is being investigated. Applications including pharmaceutical analysis, gem and mineral identification, and advanced techniques for process control are under study. Emphasis is currently being placed on approaches for rapid, sensitive simultaneous analysis of multiple trace level species.

    A variety of projects are under way in the area of mass spectrometry, including the development of improved ion sources and sample introduction techniques. Advanced vacuum ultraviolet lasers are being utilized to provide selective photoionization of specified molecules and applied to chemotherapy research.

    A program to develop new array detector technologies for mass spectrometry and ion mobility spectrometry is rapidly advancing. Current results promise to revolutionize detection schemes for both techniques.
