    Ambient air monitoring by FID detection – airmoVOC BTEX

    Urban pollution is a problem that concerns more and more people in charge of public health. In large cities, car emissions are an important source of atmospheric pollution. This problem is growing as the traffic keeps on increasing. BTEX compounds are present in car emissions. It is therefore important to be able to analyze them with short analysis cycle duration and on a continuous and automatic way.

  • Gas analysis & monitoring systems for greenhouse gases analysis

    The rising levels of manmade greenhouse gases (GHGs) in the atmosphere and their resulting impact on climate is now one of the single biggest technological and environmental challenges facing the world. This makes intensified monitoring of these gases more critical than ever in order to better quantify the role of the numerous natural and manmade sources, sinks and buffers involved in the cycles of GHGs. It also enables us to objectively audit GHG fluxes at the factory, city, country and continental level....

    Ambient air and emissions monitoring of Polycyclic Aromatic Hydrocarbons – airmoC10-C20+

    Polycyclic Aromatic Hydrocarbons (PAHs) are a group of over 100 different chemicals that are known to be formed typically during incomplete combustion of organic matter at high temperature. Their major sources in the atmosphere include industrial processes, vehicle exhausts, waste incinerations, and domestic heating emissions. Due to their carcinogenic/mutagenic effects, 16 PAHs are currently listed as priority air pollutants.

    Fluoride emissions monitoring in aluminum smelters

    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...

    Gas monitoring instruments and systems for semiconductor manufacturing

    In the semiconductor manufacturing industry, various perfluorinated compounds (PFCs) are used. The emissions of the PFC compounds into the ambient air are reduced by scrubbing of the exhaust gases from the process. In this process, the Gasmet™ FTIR Gas Analyzers can be used to measure the emissions into the atmosphere and also monitor the efficiency of the scrubbers. Typically monitored PFCs in the exhaust gas include carbon tetrafluoride CF4, trifluoromethane CHF3, and hexafluoroethane C2F6.

    Gas monitoring instruments and systems for anesthetic gases

    The anesthetic gases and vapors which leak into the indoor atmosphere during medical procedures are considered waste anesthetic gases (WAGs). The exposure is of relevance to thousands of professionals in hospitals, operating theaters, patient recovery rooms, dental offices, and veterinary clinics around the world, who may be continually exposed to the waste anesthetic gases during their workday. Typical gases of concern include nitrous oxide N2O and several halogenated compounds in vapor form, such as sevofluran...

    Instruments and analyzers for spectral DNI measurements

    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.

    Instruments and analyzers for outdoor material testing

    Weathering of materials is most often an irreversible process affecting the cosmetic properties or strength of materials. This aging process is mainly driven by UV radiation, Heat and reactive elements in the atmosphere, for example chemical contamination. The plastic fabric of the product can dry and therefore weakened. The solar load can overheat the products and change material properties irreversibly. A common method to test the deterioration of materials is to expose materials to sun light and...

    Gas monitoring instruments and systems for DeNOx process control

    In most combustion process atmospheric nitrogen reacts with oxygen in high temperature conditions to produce nitrogen oxides (NOx). Total NOx production is the sum of nitrogen monoxide NO and nitrogen dioxide NO2. The emissions of these gases are controlled through setting of emission limit values (ELVs) for power plants.

  • Gas Detection Solutions for Liquified Natural Gas Detection

    Liquefied natural gas owners require improved routine monitoring of facilities for safety, economic and regulatory reasons. Leaking LNG can cause explosions leading to loss of life and property. Loss of product through undetected leaks dramatically reduces a pipeline operator’s profitability. Traditional gas detectors are slow to reach and require a labour intensive process to keep maintained. IR detectors have been used but with limited success because of cross interference from other atmospheric...

    Instruments and analyzers for DNI measurements with a pyrheliometer

    Solar Direct Normal Irradiance (DNI) represents the direct solar component and contains about 80% of the total solar energy budget on earth. Outside the atmosphere (AM0) the solar irradiance is considdered as a constant (1367 W/m2) that slightly fluctuates with a 11 year cycle. The DNI at the earth surface is highly variable due to the atmospheric conditions (clouds, aerosols, water vapor and molecules).
