Haze Monitoring

by Ecotech Pty Ltd     based in Knoxfield, AUSTRALIA

The principle cause of regional and urban haze, or visibility impairment, is light extinction caused by fine particles, sulfates, organic and elemental carbon, nitrates and crustal matter. Particles between 0.1 and one micrometers in size are most effective at scattering light, in addition to being of greatest concern for human health.

Air quality monitoring

by Metrohm AG     based in Herisau, SWITZERLAND

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.

Urban air quality monitoring

by Opsis AB     based in Furulund, SWEDEN

To measure air quality in the ambient air is a challenge. The monitoring site needs to be representative and not dependant on changes in local traffic. A large number of gaseous components need to be measured with high accuracy and high availability.

Perimeter Ambient Air Monitoring

by Cerex Monitoring Solutions, LLC.     based in Atlanta, GEORGIA (US) (USA)

Cerex Multi-Gas Open Path Analyzers are available in both FTIR and UVDOAS technologies to meet specific requirements for perimeter ambient air quality monitoring, leak detection, fugitive emissions monitoring and ambient air quality monitoring. Cerex multi-gas analyzers offer significant advantages over single gas analyzer arrays, electro-chemical sensor arrays and time integrated air sampling hardware

Continuous emissions monitoring for mercury monitoring

by Opsis AB     based in Furulund, SWEDEN

Waste incinerators, cement plants and power plants need good and reliable measurements of total gaseous mercury. The measurement of total gaseous mercury is a challenge due to chemical reactions and contamination. The installed systems will often require a lot of maintanence still not giving reliable results.

Industrial solutions for air quality monitoring

by Advantic Sistemas y Servicios S.L     based in Alcobendas, SPAIN

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.

CO2 / CO Monitoring in Air

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

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.

SO2 Monitoring in Air

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

SO2 (sulfur dioxide) is measured in a number of applications. SO2 is used as a food grade preservative and must be regulated in accordance with government-set criteria to be safe for consumers. It is also measured in fuel exhaust to control for environmental pollution and in cement plants for process control.

CH4 Monitoring in Air

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

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 analyzer that is able to provide continuous monitoring is a perfect solution for this.

O2 Monitoring in Air

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

Oxygen (O2) is a colorless odorless gas, essential to all life on Earth but damaging in high concentrations. An O2 analyzer should thus be employed for safety management and air pollution prevention purposes. LasIR MP110 is perfect for continuous emission monitoring of O2. It is based on TDLAS technology and can be calibrated as an O2 analyzer, providing accurate and reliable measurements. It quickly responds to changes in compound concentration, thus providing continuous emission monitoring for the specified gas.

Dust monitoring and Sand Storm Monitoring

by Ecotech Pty Ltd     based in Knoxfield, AUSTRALIA

The frequency and intensity of dust and sand storms in many parts of the world are steadily increasing due to droughts and climate change. The severity of such storms is anticipated to increase over the coming years. These dust storms may last hours or days and cause huge damage and imposed a heavy toll on society with its physical effects, such as visibility reduction, heavy winds, red sky, hailstone and severe lightning. Such Dust storms, have a negative impact on human health, and industrial products and activities. They reduce visibility, layer on skin and cloths, infiltrate buildings and find their way into food and drinking water leaving a permanent sandy feeling in your mouth. Traditional dust monitoring instruments whether they be purely filter based gravimetric samplers or continuous monitors utilising Tapered Element Oscillating Microbalance (TEOM) or Beta Attenuation (BAM) simply are unable to cope with the high dust loads created by these storms. The filters on these instruments are quickly clogged and no further measurements are possible until a service technician visits to replace filters and filter tapes. In dust storm events this is impossible. Therefore, over the past few years a need for alternate technology which are non filter based, can cope with extremely high dust loads, require minimal maintenance and can operate off solar power has been employed in regions such as the Gobi Desert of China for the continuous monitoring of dust storm events. These instruments have demonstrated that an instrument can measure dust storm events with maintenance performed only once every 12 months. That it is possible to communicate remotely and that these systems can not only provide an early warning for dust events but have the accuracy and sensitivity to be an extremely useful tool in gauging hourly changes of visibility. Infact such instruments have been utilised by a number of EPAs around the world, including all Australian EPAs for the purpose of measuring ambient visibility as well as providing an accurate indication of rising dust events.

Portable Stack Monitoring

by Boreal Laser Inc.     based in Edmonton, ALBERTA (CANADA)

Many industries are required to measure stack emissions of toxic gases periodically, but not continuously. Extractive wet chemical methods currently used are slow, labor intensive and expensive.

Air monitoring for laboratories

by GE Healthcare UK Limited     based in Little Chalfont, UNITED KINGDOM

Many of the air quality analyses can be performed with standard laboratory consumables, such as traditional filter papers. However, some analyses require materials with specific features, for example filters with low metal levels.

Common air monitoring applications include:

  • Air quality testing of ambient environment and emissions. Includes particulate monitoring methods such as PM2.5 and PM10, and chemical analysis such as heavy metals determination.
  • Asbestos sampling and analysis
