Research focuses on developing and applying separation techniques (e.g., gas chromatography [GC], liquid chromatography [LC], supercritical fluid chromatography [SFC], capillary electrochromatography [CEC], and capillary electrophoresis [CE]) for trace level determination of organic and organometallic compounds. Research interests include (1) developing extraction systems for selective removal of analytes from natural matrices (e.g., pressurized fluid extraction [PFE], microwave-assisted extraction, and solid phase microextraction); (2) developing chromatographic and electrophoretic approaches for sample preparation/cleanup and analyte preconcentration prior to analysis by LC, GC, SFC, CEC, or CE; (3) developing off- and on-line multidimensional separation procedures (e.g., LC-GC, LC-LC, and LC-CE) to measure individual species in complex mixtures; and (4) developing and using simultaneous multiple and/or selective chromatographic and electrophoretic detection systems (e.g., mass spectrometric, electron capture, flame photometric, ultraviolet-visible diode array, fluorescence, electrochemical, and chemical reaction detectors) to enhance measurement selectivity and/or sensitivity. Recent activities have emphasized applications in environmental, clinical, and forensic areas including the determination of (1) environmental contaminants such as polychlorinated biphenyls, polycyclic aromatic hydrocarbons, pesticides, dioxins, toxaphene, flame retardants, and organometal species in natural matrices such as sediment, tissue, human serum and milk, and air particulate material; (2) nutrients such as vitamins and carotenoids in food and serum; (3) drugs of abuse in urine and hair; and (4) biomolecules such as proteins, peptides, and DNA fragments. Research opportunities also exist to apply these separation techniques to trace inorganic analysis problems.
