Air Monitoring Dioxin Emission Continuous Sampler
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 a 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 1948 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. The control unit is the user’s interface that controls all system’s functions; it is usually located in a safe and easily accessible area.
Built in an industrial cabinet, it’s connected to the sampling unit through pneumatic and electrical connections. DECS manage the sampling fully in automatic, without man supervision.
Available interfaces are a 10” LCD graphic monitor, a keyboard, a compact flash and a Internet/Ethernet connection. Once the measurement is terminated, a summary report is produced, in order to calculate the concentration and evaluation of the measurement quality; a continuous record of the main parameters and anomalous situations it is also available. Extensive data log can be downloaded via a USB key compact flash.

Reliable Turnkey Gas Emission Monitoring System
Loccioni’s (Italy) GCS (GIGAS CEM SYSTEM) is the turnkey system for gas emission monitoring and process control, it is a rugged and modular system, to be easily integrated in any supervisor level of an industrial plant.
GCS includes the reliable and accurate GIGAS 10M FT-IR analyser, a pneumatic chain for gas sampling and conditioning, components for a complete automation and a built-in industrial PC with touch screen to control the whole system. This is made possible by Loccioni’s GasCalc software, the complete and integrated solution for the management of the measuring system.
GCS performances have been tested and approved by TÜV Rheinland, in compliance with current European standard EN 15267 and old standards EN 14181 and EN 14956: the official test report contains any detail about laboratory and field tests.
The GCS offers dynamic real-time alignment of the interferometer optics to be stable against vibrations, spectral shift and thermal or mechanical shocks. The unit’s modular layout means that various accessories can be coupled with the same interferometer bench module to satisfy all client specifications. GCS also offers a large spectral library, combined with spectroscopic competences, to identify and quantify over 300 chemical compounds. A multipath optical cell with proper coating and over-coating to be resistant to the harshest environmental and process conditions makes the GCS reliable, even in the worst possible conditions. This instrument is easy to start up, operate and service on-site. Moreover the GCS includes reliable, user-friendly software which can be configured according to specific needs. Loccioni are currently looking for selling partners throughout the E.U.
