Description:
The U.S. Environmental Protection Agency, through the Environmental Technology Verification Program, is working to accelerate the acceptance and use of innovative technologies that improve the way the United States manages its environmental problems. This report documents demonstration activities, presents demonstration data, and verifies the performance of the Sentex Sentograph Plus II field-portable gas chromatograph. Reports documenting the performance of the other technologies have been published separately. The demonstration was conducted at two geologically and climatologically different sites: the U.S. Department of Energy's Savannah River Site, near Aiken South Carolina and McClellan Air Force Base, near Sacramento California. The demonstration provided adequate analytical and operational data with which to evaluate the performance of the Scentograph Plus II gas chromatograph. The Sentograph Plus II costs about $35,000 for a single-detector, single-column configuration, and can be operated by a field technician with minimal training in gas chromatography.
Under appropriate application, the Sentograph Plus II can provide useful, cost-effective data for environmental site characterization and routine monitoring. As with any technology selection, the user must determine whether the technology is appropriate for the application by taking into account instrument performance and the project's data quality objectives.
