Development of a Complete, Fully Autonomous On-line Cabinet Solution for Continuous Monitoring of Odorous Compounds

The presence of odorous compounds presents issues for both ambient air pollution and specific industrial processes. Monitoring these odorous compounds is important because some of them have adverse effects on human health, on the environment and process efficiency even at very low concentrations. In industrial areas, many odorous compounds, such as Volatile Organic Compounds (VOCs), can be emitted, in a wide range of concentration and specific identification and quantification of all these molecules can be a challenge given the number of potential interferences. The goal of this study is to present a complete and fully autonomous on-line cabinet solution for the continuous monitoring of odorous compounds. This solution is composed of several Gas Chromatographs (GC), each specifically designed to target some VOCs and/or odorous compounds. Gas generators were also used, allowing a complete autonomy of the system. All analytical systems and gas generators were integrated in two airtight and waterproof cabinets regulated in temperature. This complete and fully autonomous solution is ideal for industrial processes operating in harsh environmental conditions, ensuring accurate and continuous results.
