The performance evaluation of innovative and alternative environmental technologies is an integral part of the U.S. Environmental Protection Agency's (EPA) mission. In the spirit of the technology policy, the Agency began to direct a portion of its resource toward the promotion, recognition, acceptance, and use of U.S.-developed innovative environmental technologies both domestically and abroad. The environmental Technology Verification (ETV) Program was created by the Agency to facilitate the deployment of innovative technologies through performance verification and information dissemination. The performance verification contained in this report is based on the data collected during a demonstration of a field portable gas chromatograph/mass spectrometer (GC/MS) system. The demonstration was administered by the Consortium for Site Characterization Technology. For each pilot, EPA utilizes the expertise of partner 'verification organizations' to design efficient procedures for conducting performance tests of environmental technologies. In 1995, the Consortium conducted a demonstration of two field portable gas chromatograph/mass spectrometer systems. The Bruker-Franzen EM640TM GC/MS consists of a temperature-programmable gas chromatograph coupled to a mass spectrometer. Overall, the results of the demonstration indicated that most of the performance goals were met by the Bruker GC/MS system under field conditions. Based on the results of this demonstration, the Bruker EM640TM CC/MS system was determined to be a mature field instrument capable of providing on-site analyses of water and soil gas samples comparable to those from a conventional fixed laboratory.
