Total Reactive Nitrogen (NOy) monitoring

by Ecotech Pty Ltd     based in Knoxfield, AUSTRALIA

NOy (total reactive nitrogen) is defined as the sum of NOX plus the compounds produced from the oxidation of NOx which include nitric acid. NOy component species include NO, NO2, NO3, HNO3, N2O5, CH3COO2NO2(PAN), and particulate nitrate.

Nitrogen Oxides (NOx) monitoring

by Ecotech Pty Ltd     based in Knoxfield, AUSTRALIA

Oxides of Nitrogen (NO/NO2/NOX) is the product of endothermic reactions within combustion engines and causes significant environmental pollution. The main source of NOX is from the engine of automobiles and these pollutants are harmful to humans in their respective forms or in the creation of ozone (O3) or acid rain. NOX is most prevalent in our societies as a contributor to asthmatic conditions as well as the photochemical smog found throughout many industrialized cities.

NH3 Monitoring in Air

by Unisearch Associates Inc.     based in Concord, ONTARIO (CANADA)

NH3 (Ammonia) is a colorless gas with a distinctive pungent smell. Ammonia monitoring is essential in coal-fired power plants, where NH3 is used to reduce NOx emissions. The ammonia consumes all of the NOx, but its high concentration that is needed for these purposes also starts reacting with other things and in the process can clog up filters and cause premature failure of expensive SCR equipment and pre-heaters. Not to mention that these high levels create an irreparable damage to the environment.

PTR-TOFMS systems for automotive real-time vehicle exhaust analysis

by Ionicon Analytik Ges.m.b.H.     based in Innsbruck, AUSTRIA

Monitoring exhaust gas from combustion engines, emitting a large number of different compounds and with rapidly changing concentrations due to variations in operating conditions, necessitates an instrument that measures in real-time and with high sensitivity – an IONICON PTR-TOFMS.

Non-Standard Applications

by Procal - Parker Hannifin Corp     based in Peterborough, UNITED KINGDOM

Procal supply analysers to monitor many different applications from small combustion plants to large power stations. Examples include University Boiler Plants, Carbon Black Plants, Thermal Oxidisers and Community Heating Projects.

Emissions Monitoring for Tunnels

by Opsis AB     based in Furulund, SWEDEN

The Opsis monitoring solution is designed for high-quality gas measurement in traffic tunnels. The monitoring systems have been approved by the Germany TÜV and the U.S. EPA among others.

Emissions testing for engines

by Testo Inc.     based in Sparta, NEW JERSEY (USA)

Rich-burn engine exhaust, when uncontrolled, can have wide concentration ranges and both CO and NOX can fluctuate significantly. The on-board CO dilution system will automatically set-up for optimum testing, perfect for a rich burn engine. Lean-burn engines have different exhaust characteristics, but NO2 can make up a significant portion of the total NOX measurement. The 350 measures both NO and NO2 for proper lean-burn engine set-up. Due to high concentration, replaceable interference filters keep the sensors stable and your readings accurate. High exhaust pressures and heavy particulate loading are easily controlled with the special pressure relief valve (standard) on the engine probe configuration.

Emissions Monitoring for Cement Plants

by Opsis AB     based in Furulund, SWEDEN

Opsis provides state-of-the-art monitoring equipment, fully meeting the high standards of monitoring performance and reliability that the cement industry requires. The Opsis in situ systems are designed to withstand environments with high particulate levels and high temperatures.

Emissions Monitoring for Mineral Wool Production

by Opsis AB     based in Furulund, SWEDEN
