The United States Department of Energy (DOE) has identified the need to measure dioxin/furans in real or near real time in stack gases to meet the Environmental Protection Agency’s (EPA) Maximum Achievable Control Technology (MACT) Standard. As part of a preliminary evaluation of promising technologies such as fast chromatography a mixture of various dioxin/furans was sent to Electronic Sensor Technology for evaluation using a GC/SAW. This report includes a description of the GC/SAW measurement system, sample analysis procedures, calibration procedures, values obtained and minimum detection levels.
