POST-DOCTORAL POSITION AT U.S. EPA, RESEARCH TRIANGLE PARK, NC -
Application Deadline March 31, 2001.
DETECTION OF AIR TOXICS USING RESONANCE ENHANCED MULTIPHOTON IONIZATION
AND TIME OF FLIGHT MASS SPECTROSCOPY
Chemical Physicist/Physical Chemist with experience in the use of
laser-based spectroscopic methods for measurement of gaseous species.
The ideal candidate will have hands-on experience with resonance
enhanced multiphoton ionization (REMPI). The candidate will work in an
applied program that couples REMPI with time-of-flight mass spectrometry
(TOFMS). The candidate will work with the leading international laser
spectroscopy groups developing the REMPI analytical method for use at EPA.
Candidate will apply REMPI instrument for detection of trace halogenated
air toxics as part of a comprehensive program at the EPA's combustion
research facility in Research Triangle Park, NC, investigating the
formation mechanisms of these pollutants. U.S. citizenship is required for
this position, and applicants should be either soon-to-be or recent (past
five years) PhD's.
Background
The U.S. EPA's Office of Research and Development, National Risk
Management Research Laboratory (Research Triangle Park, NC) conducts
research on formation mechanisms, quantification methods, and prevention of
hazardous air pollutants, particularly halogenated organics such as
chlorinated dibenzodioxins/dibenzofurans, biphenyls, and naphthalenes.
Recently, NRMRL has been awarded a grant to study the application of
REMPI/TOFMS techniques toward development of a real time "dioxin" monitor.
This grant program, combined with a DOE-funded program to develop the
instrumental science behind REMPI/TOFMS, constitutes a large
federally-funded effort whose goal is to develop this method of hazardous
air pollutant detection for source characterization, understanding of
pollutant formation mechanisms, and pollution prevention. As part of this
program, a REMPI/TOFMS system has been built and is located for use at
EPA's combustion research facility. The post-doctoral laser
spectroscopist is necessary to operate the REMPI/TOFMS system and develop
its application for trace halogen detection. Candidate will work with a
team of researchers investigating hazardous air pollutant formation on
in-house facilities including waste combustors, industrial boilers, solid
fuel combustors, rotary kilns, and laboratory reactors.
