to present information
Continuous samplers and real or semi-real-time continuous monitors for polychlorinated dibenzodioxins and furans provide significant advantages relative to conventional methods of extractive sampling. Continuous samplers collect long term samples over a time period of days to weeks and produce a cumulative record of emissions performance and provide evidence of systemic problems in air pollution control systems. The frequency of measurements typically depends on the indicator concentration, ranging from real-time to about an hour. This response frequency allows them to be used for process diagnostics, providing fast feedback to the plant operator. Several companies are developing these monitors, however the performance of the newly introduced technologies has not been evaluated. EPA's Environmental Technology Verification program Advanced Monitoring Systems Center decided in early 2005 to test the performance of continuous dioxin samplers and real and semi real-time continuous dioxin monitors to generate performance data for the four dioxin emission monitoring systems participating in the test. The accuracy and range of the four systems were determined.
