The recent COP 21 meeting reexposed the need for global coordination to monitor Green House Gases (GHG) as well as emissions of ChloroFluoroCarbons (CFC). Networks of sensors have been deployed over the Earth to measure concentration of gases such as methane, carbon monoxide, ethane, carbon dioxide, nitrous oxide, nitrogen oxide and dioxide (NOx)… Such task requires instrument with not only ultra high accuracy but also ultra high precision. Our QCNose Instruments have been...

Introduction: Accurate control of critical indoor environmental parameters is not only essential for the well-being and comfort of building occupants, but also has a major impact on energy efficiency. A multitude of parameters can affect indoor air quality (IAQ) from gases such as carbon dioxide, carbon monoxide and volatile organic compounds to particulates, humidity and bacteria such as legionella. Carbon dioxide is one of the greatest variables affecting indoor environmental quality since it is produced by...
CH4 (Methane) is a colorless, odorless natural gas that is used in a wide variety of industrial applications such as power generation and chemical production. It is also a byproduct of many biological and geological processes, fracking, and gas drilling. It is highly flammable and creates amounts of carbon monoxide as its combustion byproduct. Methane needs constant monitoring in waste water treatment (for co-generation) and to ensure proper process control (e.g. to determine burning efficiency). A quality CH4...

CO (carbon monoxide) and CO2 (carbon dioxide) are generally measured to ensure process control. CO2 is the desired product and CO is undesired in combustion since it will explode in high enough concentrations. CO2 and CO concentrations can also be used to determine other process-specific efficiencies. Continuous emissions monitoring equipment that can be calibrated as a CO and CO2 analyzer is thereby essential for process control.

Production of aluminum from its ores at aluminum smelters results in carbon dioxide CO2, carbon monoxide CO, sulfur dioxide SO2, and hydrogen fluoride HF gas emissions during the electrolytic process phase to the atmosphere. The gas emissions need to be monitored. Typically the smelters have emission limit values (ELVs) for sulfur dioxide and hydrogen fluoride emissions. These emissions should be measured accurately and with good precision, to ensure the smelter does not exceed its emission limit values. In...Premium
Nitric acid HNO3 is an important intermediate reagent for production of several important end products, such as fertilizers, explosives, dyestuffs/pigments, pesticides, pharmaceuticals, photographic materials, plastics, and synthetic fibers. At nitric acid manufacturing plants, the Gasmet™ FTIR Gas Analyzer can be used to measure several gaseous components from the process stream for purposes of process control. A single system can be used to measure the high levels of nitrogen monoxide NO and nitrogen...Premium
Compressed breathing air is subject to strict limits of harmful contaminants defined in European standard EN 12021 and various defence standards such as DEF STAN 68-284 issue 3. The testing interval of breathing air compressors and associated equipment is 3 months and gases tested include carbon monoxide, carbon dioxide and oil vapour defined as hexane and heavier hydrocarbons. EN 12021 covers underwater applications including self-contained open circuit compressed gas breathing (SCUBA) and compressed gas line...Premium
Gas monitors controlling heat treatment of metals. Endothermic gas is a mixture of carbon monoxide, carbon dioxide, methane and other gases that is required for hardening or carburising of steel. By carefully controlling the amounts of each gas and the temperature in the treatment furnace, the steel surface can be hardened to provide long lasting components such as gears and tools.
