Abstract : There is a universal need within defense-related operations fo r chemical sensing. It is most desirable for the detector (i.e. probe) to operate in situ and to produce information on chemical composition in real time with a high degree of sensitivity (ppb or less). It is the goal of this work to develop a 'universal' remote sensor for organic and inorganic compounds in both gaseous and liquid environments, based on surface enhanced Raman spectroscopy (SERS). The SERS signal is observed as the enhanced Raman spectrum of molecules absorbed onto certain active metal substrates. The goal of Phase I was to determine the feasibility of using SERS in gas phase sensing. Keywords: Fiber optic, Sensor, Raman, Air quality, Groundwater, Environment. (mgm)
