This is a report summarizing work on a small project dedicated to adapting a new chemical sensing platform for the US Department of Energy and its customers. At the same time and in the spirit of technology transfer, FCI Environmental, Inc., would receive technical support in the form of expertise from the US Department of Energy to assist in developing this product. The sensor is a hybrid integrated-circuit, optical waveguide, chemical sensor that is patented by FCI Environmental, Inc., and manufactured under license by Texas Instruments, Inc. A down-hole penetrometer probe was designed for use in hot, 60 C, hydrocarbon-saturated, saline environment at a depth of 200 feet. The probe design includes three chemical sensing, hybrid integrated-circuits with chemical reference and measurement channels, a water seal, output electronics, and a removable measurement head for replacement in the field. A hand-held chemical detector prototype--containing a hybrid integrated-circuit chemical sensor with reference channel, user alarm, and level display--was designed and constructed, and a software interface developed to operate the hand-held sensor interfaced with a laboratory data acquisition system
