Research Interests

The overall goal of our research is the development of supercritical fluid extraction (SFE) technology as an efficient, cost-effective, and environmentally "friendly" alternative to traditional solvent-based sample preparation methods in clinical and/or forensic toxicological applications. Current projects include the development of 1) a rapid screening method for isolation and detection of drugs of the amphetamine class from human hair using on-line derivatization/SFE and GCMS, and 2) a method based on SFE/LC-MS for the isolation, identification, and quantification of anabolic steroids from human hair. Previous work involved the development of SFE/GC-MS and SFE/immunoassay methods for the analysis of cocaine in hair. Underlying objectives of our research include the investigation of the interactions which occur among analytes, biological matrixes, and supercritical fluids (SFs) and the mechanisms and kinetics that control these interactions; elucidation of the role of fluid modifiers and additives in improving analyte extractability; and the design of alternative coupled SFE-detection formats to produce rapid, simple screening methods for use in forensic or clinical laboratories.
