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...
According to US EPA IO - 3.3 standard method of heavy metals, PMMS – 5000 uses XRF nondestructive testing technology and atmospheric automatic enrichment technology to realize the accurate measurement of atmosphere heavy metals such as lead, mercury, cadmium, chromium, arsenic, etc. It is widely used in environmental air quality monitoring places such as industrial pollution area, residential area, city, etc.
With the application of air quality PM2.5 standards, people have a clear understanding and attention on ambient air quality, countries also present clear requirements and control objectives. Due to the speeding up of development process of cities construction in recent years, unceasing expands of the urban area and population scale, sustained growth of energy demand, motor vehicle ownership, various construction projects, the situation of urban air quality improvement work is more severe.
OPSIS provides real-time, flexible monitoring of particulate matter in the ambient air. Particulate matter monitoring with OPSIS, is a cost-effective solution, is ideally suited for use in modern monitoring stations. It can be remote controlled and includes automatic calibration, features that frees time. The SM200 meets the new regulation for automatic monitoring of PM10 and PM2.5. It also meets the new regulation for particulate matter sampling on filter membranes for further analysis of cadmium, nickel, PAH...
More and more cities see an increase of air pollution caused by fine dust and hazardous PM10 and PM2.5 particulates. Our DISA-CLEAN is a street & area sweeper that efficiently uses high-powered vacuum technology to permanently remove dirt, dust, and PM10 and PM2.5 particulates. DISA-CLEAN is a dust-free alternative to conventional street sweepers but with no water needed to suppress dust.
Envirotac line of polymers are commonly used on construction sites to control dust and reduce water. When an area has been mass graded contractors will use Envirotac to treat the disturbed areas as opposed to constantly watering them. One application of an Envirotac will last years and cost nearly one penny per square foot.
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
Air is lifeblood. Daily we inhale approximately 15.000 liter. Still, the air contains invisible pollutants, which vary in its composition and concentration depending on the location. Especially the respirable particles with a diameter of less than 2.5 µm (PM 2.5) were considered to be particularly dangerous.
Dekati has 25 over years of experience in providing high end aerosol research instrumentation and sample conditioning solutions to universities, research institutes, and laboratories all around the world. Dekati® Instruments and sample conditioning systems have a long, exquisite track record of scientific publications and our in-house R&D continuously develops new are more accurate ways to characterize different aspects of aerosols. Particle size and concentration studies. Particle shape and density...
Sampling dust and particulate matter is important as dust and particulate matter can affect the health of human populations, as well as the natural environment. Dust and particulate matter can cause respiratory problems when breathed in by humans. Dust and particulates above 10 micrometer (PM10) are filtered and generally do not enter the lungs.
Dekati has over 25 years of experience in providing measurement solutions for emission measurements. Today, our selection of measurement solutions for stationary source emission measurements include both real-time and gravimetric detection of concentration and particle size distribution. Our extensive line of sample conditioning devices enable not only environmental emission measurements but also measurements directly from the combustion zone and before heat exchangers and used flue gas cleaning devices. Dekati...
By installing Dustroid around mines, quarries and construction sites, monitoring of suspended particulate matter, i.e. PM1, PM2.5, PM10, PM100 is done in real-time. The data helps in optimizing the dust-suppression process in case of excessive emissions from the sources. This data is used to generate alerts and alarms based on the custom threshold set by regulators. Using such triggers, a pre-existing dust suppression system like Mist cannons, Sprinklers, Mechanical barriers, Dust collectors, Dust Filters, etc....
Common Commercial Air Problems: Managers of large office buildings today are searching for ways to lower energy costs, improve indoor air quality, and lower a building’s environmental impact. The same is true of those responsible for school, university, healthcare, health club, and hospitality facilities.
Fine dust is generated by industrial exhaust gases but in particular due to traffic. Environmental pollution is therefore caused particularly by exhaust gases of diesel-engined vehicles (diesel soot) but on the other hand also by abrasion of street, tyres and brakes and its resuspensions.
Measurement of particulates, SO2, NOX, CO, hydrocarbons and greenhouse gas emissions from the mineral process industries requires careful selection of instrumentation. Ecotech offers a complete monitoring solution tailored to this industry.
