HPLC: Development of liquid separations for various analytes using porous graphitic carbon columns in both the reverse phase mode and normal phase mode. Efforts to take advantage of this unique phase which appears to be well matched to environmental analysis. Anticipatory and relevant to existing problems. Implementation of two-dimensional separations based on fractionation from C18 RPHPLC fed to porous graphitic carbon columns. Solves two problems: dilution of sample and speed required for second dimension. Addresses the need for increased peak capacity in analysis of complex matrices. Multidimensional separations provides a framework for any pesticide residue problem in environmental analysis; currently looking at HPGPC, RPHPLC, CZE, and porous graphitic carbon. Systematizes the analytical problem into one, two, or three dimensional separations depending on detector, residue level, and matrix interferences.
PCBs: Fractionation of most toxic PCB isomers with HPLC using porous graphitic carbon column. This work is being broadened to include the polybrominated diphenyl ethers.
Electrophoresis: This work has been most practically focused on groundwater tracers using LIF detection. Pharmaceuticals and Personal Care Products (PPCPs): Characterization of waste streams and detection of various compounds including base/neutrals and acids. Extension to amine containing acids as well.

Laser-induced fluorescence (LIF) and detection limits: Liquid separations and low detection limits using LIF address future anticipated problems requiring LC separations and extremely low detection limits; tie in to new high-resolution mass spectrometer and LC/MS and CE/MS techniques. Positions EPA to handle nonvolatile compounds introduced by commerce into the environment.
LIF detection using the frequency-doubled laser is being expanded in applications beyond PNAs to anionic and cationic compounds in extracts of contaminated soils. Phenols are currently under study with an emphasis on EDC candidates. LIF provides fundamental insight into exposure processes and a sensitive screening tool for mass spectral confirmation. We are establishing ourselves as a leading laboratory in this field with frequency-doubled laser, multiwavelength laser, HeCd near UV lasers, and visible region lasers with a strong tie in to the new HRMS for unknowns and characterizing biomarkers.
Developing a CE/LIF format using visible region for immunoassay using herbicides as an example target; this allows for LIF detection limits without derivatization at ppb and sub-ppb levels.
Carrying out the experiments for doing full emission spectra recording on the fly for CZE/LIF with better qualitative identification and quantitation based on the full spectrum.Sample preparation:
Solvent extraction research: Initiating fish extractions for determining background levels and reagent blanks for future sample work. Most work is planned for accelerated solvent extraction (ASE) technique with some portions undergoing SFE and Soxhlet reference extractions.Environmental Monitoring:
EDC Screening: Developing a RT data base for common target compounds for EDCs using GC/ECD and GC/NPD to supplement screening and GC/MS analyses.
Pesticides: Developing a microbore HPLC multi residue screening procedure for 50 to 100 pesticides likely to be encountered from high density agricultural activity such as in California San Joaquin Valley. HRMS: New HRMS involving CE/MS and LC/MS projects especially in the context of multiresidue analysis.Why it is important Methods development (and the overall role of analytical chemistry) is important since it undergirds the regulatory aspects, the cleanup, and the understanding of the environment. Methods are found explicitly in the numbered U.S. EPA Methods that are known worldwide for reliable environmental analysis. Continuous improvements to methods are recognized in the ORD Strategic Plan for improving the reliability of environmental measurements, for lowering costs of analyses, and for reducing worker exposure while simultaneously reducing waste production from the analytical operations. New substances continuously enter the environment as they become new members of the chemicals of commerce. Many of these are specifically earmarked for environmental applications or become of environmental interest due to their applications in related fields of medicine, food, water treatments, crop control, and industrial use. Methods are subject to continuous improvements in techniques, technology, and invention of new tools as is any field of science and technology. Our role in ORD is both short range and long range. Short range goals include improvements to existing methods that respond to research needs that we as experts perceive, needs created by new program initiatives such as EDCs and DISPro, needs stated by program offices, and needs prioritized by regional scientists. Longer range goals include our role of capturing the best of the new developments and new tools emerging in diverse areas of chemistry, biochemistry, physics, and biology. It is recognized that biochemistry and the biomedical fields have currently stimulated much growth in instrumental capabilities to enable the solution of difficult analytical problems. This growth has in turn stimulated our own efforts to develop liquid separations and their interfacing to mass spectrometry as well as our efforts to study the fundamental biochemical indicators of exposure including biological specimens and proteins.
