    Air quality monitoring

    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.

    Air monitoring for laboratories

    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

    Gas analyzers for clean air room monitoring

    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.

    Capabilities of the Adsorbent Tube Injector System (ATIS™)

    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...

    Industrial monitoring solutions for the dust collectors areas

    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...

    Formaldehyde and Acetaldehyde Determination in Air Using Fully Automated On-Line Desorption and Analysis of DNPH Cartridges

    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...

    Emission control & air dedusting for Fertilizers

    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.

    Environmental solutions for the flue gas temperature control

    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.
