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.
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
The ambient air in clean air rooms needs to be constantly monitored for the safety of workers and of the production according to the environment. A clean air room is a room where the concentration of particles is controlled in order to minimize the introduction, the generation, retention of particles inside, for instance for chip production or the production of medicines.
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.
The Adsorbent Tube Injector System (ATIS) was developed at Supelco® by R&D Scientists, as a tool to assist in our comprehensive adsorbent research for thermal desorption tubes. The ATIS provides an efficient means of transferring calibration standards in either the gas or liquid phase onto the adsorbent packed tubes.
The ATIS employs the technique of flash vaporization to vaporize the sample in a continuous flow of inert gas; the inert gas carries the sample to the tube. The sample pathway of the ATIS is construct...

Most industrial processes have dust collectors of some form or other, the most popular being filter bag houses. Very few of these are covered by regulation other than to have a broken bag detector to prevent nuisance dusts escaping and creating a local nuisance. The CODEL StakGard is a low cost Tribo-electric monitor that directly measures mass particulate concentration by sensing the frictional charge created when particles collide with a conductor. The advanced electronics of the StakGard detect this signal and...
Airborne aldehydes and ketones are collected by passing air through a cartridge containing 2,4-dinitrophenylhydrazine (DNPH). Carbonyl compounds react with the DNPH to form hydrazones, which are immobilized on the cartridge. These compounds can be easily eluted from the cartridge with acetonitrile and analyzed by HPLC with UV detection. Traditionally, this analysis including the workup contains a series of manual steps, which can become time-consuming and could incur experimental error.
Automating the extraction...
One-time, on-site final destruction of particulates. This is the key benefit gained from an Anguil solution to the emissions generated by the rubber curing process. Other advantages of an Anguil solution include the elimination of visible blue haze, guaranteed destruction efficiency compliance, and the elimination of costly mechanical filtration media and the lingering liability issue associated with filter disposal.
Production of semiconductor materials require extremely clean air supply that help ensure the quality of the materials being manufactured as well as specialized gases to enable production to occur smoothly and efficiently. Teledyne API carries a complete line of Industrial gas process instruments including those that both produce and measure gases in these unique applications. Teledyne API also provides specialty gas instruments designed to help reduce or eliminate Airborne Molecular Contamination (AMC) in the...
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...
The recovery of fertilizers typically after drying tunnels or drum dryers is associated with a high load of particulates and very humid gas streams. The recovery of these products is commonly performed by dryer cyclones as they allow for a direct powder capture and avoid filter clogging due to condensation. Arrangements with cyclones and/or with bag filters are usual in the industry.
Anguil`s engineering expertise has led to numerous successful air pollution control and emission control installations in the automotive manufacturing industry. From painting vehicles to engine test stations and tire manufacturing, we have supplied oxidizers and heat recovery systems to both tier 1 and tier 2 automotive plants.
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.
Dekati® Solutions for air quality particle measurements include both air quality monitoring and atmospheric aerosol research instruments. Our aerosol measurement solutions have been successfully used in various ambient aerosol research and monitoring areas for over 25 years and today, our instruments are used globally by thousands of customers both in research and industry to measure different properties of airborne particles
Compressed air isn`t free, so more and more companies carefully monitor and control its usage. We manufacture a range of thermal mass flow meters and vortex flow meters that are ideal for accurate compressed air monitoring.

Evaporative gas cooling and conditioning systems help protect your downstream equipment, enhance air pollution control performance, reduce gas volumes, and increase production capacity. Central to our systems are Turbotak atomizing nozzles, which introduce a controlled amount of finely atomized water into the hot gas stream to reduce and/or maintain gas temperature. The water evaporates, while absorbing heat from the gases, for free-flowing dust, zero liquid discharge, and minimal or no wall buildup.
The radiello ammonia sampler impregnated with phosphoric acid represents a low-cost, reliable and simple tool for assessing the atmospheric deposition of ammonia at parts per billion (ppb) concentration levels.
