In Brief Nitrous oxide (N₂O) is a potent greenhouse gas produced during biological nitrogen removal in wastewater treatment. Emission factors vary widely between plants and over time, making continuous, real-time monitoring essential for accurate carbon footprint...
In Brief Wastewater treatment facilities generate gas-phase ammonia at nearly every process stage, from headworks through aeration, scrubbing, and sidestream dewatering. Uncontrolled NH₃ emissions contribute to eutrophication, pose health risks, and indicate...
In Brief Ammonia emissions from livestock housing, manure storage, and fertilizer application contribute to eutrophication, secondary particulate matter formation, and occupational health risks. Monitoring NH₃ across the barn-to-field chain requires analyzers that...
In Brief Tunable diode laser absorption spectroscopy (TDLAS) analyzers differ from electrochemical (EC) and catalytic bead sensors in response time, calibration requirements, maintenance burden, sensor lifespan, chemical selectivity, and diagnostic capability. For...
In Brief Fugitive emissions from valves, flanges, tanks, and buried infrastructure represent both a compliance liability and a direct product loss. TDLAS-based gas analyzers address the core measurement challenge in leak detection and repair (LDAR) programs: covering...
