Laboratory for
Plasma Spectrochemistry,
Laser Spectroscopy
and Mass Spectrometry
Welcome! Research in the Laboratory for Plasma Spectrochemistry, Laser
Spectroscopy and Mass Spectrometry includes fundamental studies of plasmas
used for elemental analysis, aerosol generation and processing, development
of new techniques for elemental speciation and application of analytical
measurement techniques to environmental and geological problems.
On-going experiments range from laser induced fluorescence image detection
of individual clouds of atoms and ions produced from a single drop of solution
(an atom cloud is shown to the left), to investigation of electrospray and ion spray processes
that lead to sampling of intact ions from solutions, to measurement of
metal-ligand complexation systems that are important in metal pollutant
transport and remediation. We'll be putting some of our latest, most exciting
results (including some beautiful images and later, movies), software and
useful links to other interesting information on this page, so visit us
often.
