Environmental Technology Verification Report: Photoacoustic Infrared Monitor,211 Innova AirTech Instruments Type 1312 Multi-Gas Monitor

摘要

The U.S. Environmental Protection Agency. Through the Environmental Technology211u001eVerification Program, is working to accelerate the acceptance and use of 211u001einnovative technologies that improve the way the United States manages its 211u001eenvironmental problems. This report documents demonstration activities, presents 211u001edemonstration data, and verifies the performance of the Innova Type 1312 Multi-211u001egas Monitor. Reports documenting the performance of the other technologies have 211u001ebeen published separately. The demonstration was conducted at two geologically 211u001eand climatologically different sites: the U.S. Department of Energy's Savannah 211u001eRiver Site, near Aiken, South Carolina and McClellan Air Force Base, near 211u001eSacramento California. The demonstration provided adequate analytical and 211u001eoperational data with which to evaluate the performance of the 1312 Multi-gas 211u001eMonitor. A correlation analysis of 1312 and laboratory TCE and PCE groundwater 211u001eresults revealed a relatively high degree of linear correlation for Savannah 211u001eRiver data (r > 0.98) and McClellan data (r>0.89). The type 1312 costs between 211u001e$28,000 and $35,000, depending on options, and can be operated by a field 211u001etechnician with minimal training. Method development and analysis of multi-211u001ecomponent samples may require a higher level of operator training and knowledge 211u001ein use of the instrument. The throughput rate was in the range of one or two 211u001esamples per hour. Analytical results are available at the conclusion of a sample 211u001erun. The results of the demonstration show that the 1312 can provide useful, cost-211u001eeffective data for routine groundwater monitoring in circumstances where the 211u001esample composition in known. As with any technology selection, the user must 211u001edetermine what is appropriate for the application by taking into account 211u001einstrument performance and the project's data quality objectives.
