Carbon Dioxide (CO2) lasers are high power lasers, usually used for cutting of ferrous and non-ferrous metals. High-performance gas flow control is a key requirement for achieving high cutting performance with CO2 lasers. Gas flow control plays an important role for mixing key gases at a number of locations with a CO2 laser: Beam Generation: The gas mixture used as the emitting medium usually consists of CO2, He and N2. Most laser manufacturers specify a minimum required purity for the beam generation gas...

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...
Application: Anaerobic Digestion plants produce various gas components from a source material (or feedstock) that can be composed either solely or as a mixture of slurries, purpose-grown crops, food and organic waste material. The composition of the gas produced varies depending upon the feedstock and the Anaerobic digestion process itself. As a consequence, it is normal to measure various components of the resultant gas produced to evaluate the efficiency of the Anaerobic Digestion process. Furthermore, due...
Thermal mass flowmeters are ideal for Carbon Dioxide metering and mass flow control. Sierra specializes in accurate mass flow measurement and/or control of CO2 gas. Applications range from general industrial process control across numerous industries to Green House Gas monitoring requirements and general research.

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...

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.

Biodegradation tests involve testing samples in response to various parameters: dilution, nutrient addition, pH, temperature, and others. The pattern of oxygen uptake in aerobic tests; nitrogen gas production in anoxic denitrification tests; methane production in methanogenic tests; hydrogen production during glycolysis; and carbon dioxide production during fermentation reactions gives a measure of the rate and extent of biodegradation of the organic constituents of the test sample.

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
Our range of gas monitoring instruments are used to measure the constituents of Biogas and monitor Landfill sites for Methane (CH4), Carbon dioxide (CO2), Hydrogen sulphide (H2S), Carbon Monoxide(CO) and Oxygen (O2).

Where the pyrheliometer is most suitable to quantify the total DNI of the solar spectrum. The spectroradiometer gives details about the energy distribution which is important for PV or CPV cell research. The solar spectrum wil change with the angle of incidence and its path through the atmosphere. Photons wil be reflected, scattered or absorbed. Big absorbers of infrared irradiance are water vapor, carbon dioxide, and ozon.

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.
“Biogas” means a mixture of various types of gas (mostly methane) produced by bacterial fermentation in anaerobic conditions(absence of oxygen) of organic residues from waste, decaying plant, carcasses in putrescence. The analyzers of biogas by Infrared cells carry out the continuous analysis of CH4, O2, CO2, H2S and NH3. The whole process sees the decomposition of organic material by some types of bacteria, producing carbon dioxide, molecular hydrogen and methane(methane conversion of organic...
