Ambient air quality monitoring at airports
by Opsis AB based in Furulund, SWEDENTo measure the ambient air quality at airports is a challenge. The monitoring site needs to be representative for background levels and not dependant on changes in local traffic. A large number of gaseous components need to be measured with high accuracy and high availability. The OPSIS DOAS system provides the user with a fast system that gives high availability at low cost. The impact of aircraft take-offs and landings can easily be followed on-line. The OPSIS system can also monitor fugitive emissions from other sources at the airport.
Measurement of diacetyl in ambient air to monitor workplace exposure limits.
by MOCON - Baseline based in Lyons, COLORADO (USA)The Series 8900 Diacetyl Analyzer provides direct measurement of Diacetyl in ambient air. This instrument is utilized for environmental monitoring and to monitor workplace exposure limits. The Series 8900 Analyzer for Diacetyl employs a photoionization detector (PID) as the sensing element. A dual column configuration with timed backflush to vent is used to strip off moisture and heavier hydrocarbons. A pre-cut column is used in series with the analytical column. At sample injection a fixed volume of sample is carried to the pre-cut column. Backflush is timed so that only the Diacetyl and other similar components are eluted to the analytical column. Contaminants on the pre-cut column are backflushed to vent. The Diacetyl is separated from potentially interfering components on the analytical column and elute to the detector for analysis.

Ozone monitoring
by Ecotech Pty Ltd based in Knoxfield, AUSTRALIAOzone found in ambient air can have a direct affect on human health and also has the potential to create photochemical smog. It is for this reason that the U.S. EPA has set a one hour limit of 120 ppb and an 8 hour limit of 80 ppb. Ozone has been found to affect human health by harming the respiratory and immune system. People with pre-existing respiratory damage or diseases are more likely to suffer from the affects of ozone.
Dust monitoring and Sand Storm Monitoring
by Ecotech Pty Ltd based in Knoxfield, AUSTRALIAThe 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.
Air monitoring for laboratories
by GE Healthcare UK Limited based in Little Chalfont, UNITED KINGDOMMany 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
