The increasing awareness of the dangers of compounds like dioxin, furans and POP's for human health generated a compelling need for a better understanding of dioxin stack emissions. Therefore, based on such requirements, TCR Tecora (Italy), designed and produced DECS, a Dioxin Emission Continuous Sampler, which is a1 fixed system for stack emission for determination of dioxins and furans on long term. The system is permanently installed on stack for continuous sampling from 8 hours up to 30 days. According to EN 1 948 and USEPA 23, DECS adopts the filter condenser method with adsorbing trap on wet gas. DECS consists of 2 units: the sampling unit and the control unit. The sampling unit is the part to be mounted on the stack's sampling point and its aim is the collection of the sample in its two phases (particulate and gas) without modifying its composition.
