air quality testing Applications

To estimate the effects of aerosols on health and climate, it is essential to know their chemical composition. Sampling is done using two different types of aerosol collector. The first type are filter collectors that are based on the deposition of suspended particles on surfaces; the second type are powerful aerosol collectors.

The sustainability and environmental impact of a new build house is typically assessed using BREEAM. Part of the BREEAM assessment method is determining the air quality inside the house. Gradko can supply a range of products for qualified BREEAM assessors. We try to work with qualified BREEAM assessors to determine and meet their requirements. The products we normally supply are used for monitoring formaldehye and VOC levels in new build properties.

To protect humans and the environment from damage by air pollution, it is of the utmost importance to measure the levels of pollutants in the air. Real time monitoring of dangerous gases is particularly interesting in hazardous areas, as the conditions can change dramatically very quickly, with serious consequences. ADVANTICSYS employs its knowledge in wireless sensor networks to develop customized solutions for our customers.

Motor vehicle emissions are a major source of air pollution in urban areas and impact the lives of billions of people every day around the world. Motor vehicle exhaust contains toxic chemicals that are harmful to people’s health when exposed at certain levels. These toxic fumes cause smog in the atmosphere, which can affect very broad regional air sheds and contribute to the formation of cancer. Teledyne API has several products specifically designed to meet the challenging demands of near-roadside air...

Continuous Emissions Monitoring Systems (CEMS) are used to measure flue gases from stationary sources at a wide variety of regulated industrial facilities, including power plants, petroleum refineries, petrochemical plants, waste incinerators, pulp and paper producers, and many others. The types of air pollution measured from these sources vary widely based on the industry and process, and many are regulated by government agencies around the world.

Ambient air quality monitoring is the systematic, long-term assessment of pollutant levels by measuring the concentration and types of certain pollutants in the surrounding, outdoor air. Some of these pollutants (commonly called ‘Criteria Pollutants’) are considered hazardous to human health and their levels are regulated by government agencies around the world, including the US EPA. Teledyne API provides a complete line of ambient air quality monitoring instruments, including those for both gas and...

To test gas analyzers for Air Quality monitoring, gas references must have concentration in the range of hundreds to tenths ppb. Test gas bottles with so small concentrations are expensive and unstable. With the gas divider BetaCAP30X100 it's possible to dilute high concentration test gases getting 30 dilution steps in the range from 1:100 to 1:3.000 of the original test gas bottle concentration. Traditionally MFC based diluters are used for this application, but now our capillaries based diluter is available,...

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...

The OPSIS open-path monitoring system is an excellent tool for monitoring the air quality, fugitive emissions and gas leaks at industrial sites. By arranging monitoring paths strategically at locations outside the borderline of an industrial area, fugitive emissions and gas leaks will effectively be detected. By combining the measured gas data with meteorological parameters information such as where the pollution sources are located and the strength of the emissions can be calculated, using the EnviMan software.
