The ability to measure trace and ultra-trace levels of elements is critical for mechanistic studies in environmental remediation and therapeutic drug metabolism research. Current research aims to gain a better understanding of the mechanisms of aerosol formation, solvent evaporation, particle transport and particle vaporization in the interface, in order to improve linearity and detection limits. Atomic Emission Spectrometry. The group develops new techniques for sample introduction into various plasmas for atomic emission spectrometry and use of these plasmas as detectors for liquid chromatography, in order to provide speciation information on the nature of many organometallic compounds, both naturally occurring and synthetic.
Aerosols form a major part of much of our research efforts.
We are presently studying mechanisms of aerosol formation processes and also collisional and gas dynamic processes which follow formation by laser Fraunhofer scattering, scanning electron microscopy, and laser doppler velocimetry. S. H. Pollock, J. Pharmacol.
