Title: Field Portable Fluorescence Sensor for Polycyclic Aromatic Hydrocarbons
Agency: EPA
Contract: EP-D-05-041
Award Amount: $70,000.00


In this SBIR porject, Soouthwest Scineces proposes to design, build and test a real-time, field portable instrument for detection of polycyclic aromatic hydrocarbons (PAHs). Our technology uses time- and wavelength-resolved flourescence spectroscopy (T&WFS) to identify PAHs at sub-ppb concentrations in water. The insturment incorporates an innovative approach to fluorescence lifetime detection that is based on radio frequency (rf) electronics, and is considerably less expensive than other approaches T&WFS. The Phase II prototype developed in this project will be compact, cost effective and reliable. It will use an ultraviolet diode laser for excitation of fluorescence and fiber optics to deliver and collect light at the sampling site. The entire instrument, including the diode laser optics, detector, electronics and computer, will fit into a space the size of a brief case and will br capable of running on batteries. Potential customers, in addition to the EPA, are industrial hazardous waste sites and treatment facilities, the Department of Energy for waste monitoring and remediation, and municipal waste disposal sites. Hazardous waste sites can benefit from our portable on-site assessment instrument by providing PAH contamination profiles and distributions and by providing real time monitoring during remediation efforts.
