    Urban air quality monitoring

    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.

    Air quality and industrial gas monitoring systems for Road side air monitoring

    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...

  • Haze Monitoring

    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.

    Ambient Stations for Ambient Air Quality Monitoring

    Ambient air monitoring involves the measurement of `representative` air in urban, industrial and rural areas. These measurements are used to determine the human exposure to pollutants and can be combined with trace/background monitoring.

    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 dust

    Particulate matter, suspended particulate matter, atmospheric dust, particulate matter, total suspended particulate (TSP), are terms that commonly identify the group of substances suspended in the air (fibers, carbon particles, metals, silica, polluting liquid or solid). Particulate matter is the pollutant that is now considered the greatest impact in urban areas, and is composed of all those solid and liquid particles dispersed in the atmosphere, with a diameter ranging from a few nanometers to 500 microns and...

  • Roadside monitoring

    Traffic, especially in urban locations, is one of the greatest contributors to air pollution. Traffic produces a variety of different pollutants that include particulates, NO2, NO, CO, hydrocarbons and in some cases SO2. The monitoring of roadside pollution can be challenging as often it is difficult to find suitable locations for large air quality monitoring systems and many sites that are available can be too far away to be representative of roadside air pollution.

    Low level measurement of VOCs and Terpenes close to the sea and the Landes Forest

    It has been established that organic aerosol (OA) makes up for a major fraction of fine particulate matter in all region of the atmosphere. This fraction accounts approximately for half of the total PM2.5 dry mass.1,2 Primary OA is directly emitted in the troposphere from anthropological and natural sources whereas secondary OA (SOA) is formed in-situ in the atmosphere from the oxidation of biogenic or anthropogenic gas-phase precursors and subsequent partitioning of the less volatile products into the particle...

  • Cost effective, real-time pollution monitoring networks

    Ambient air pollution is a continuous problematic since many years, and the various organizations in charge of air quality monitoring work constantly on how to improve their structures and gain the most accurate and reliable data possible. Indeed, the changes in mentality and therefore in urbanism development for example, implies an access to the data faster and at multi-location level. Air quality monitoring reference stations used nowadays measure with an extreme accuracy in located areas, but requires a lot of...
