Mercury, being widespread in environment, has toxic effect on a human organism even at a low concentration. Therefore, quantitativ e determination of mercury in vari ous environments is one of the most important environmental monitoring problems. The use of a mercury analyzer RA-915M/RA-915+/RA- 915Light with Zeeman background correction provides di rect real-time continuous determination of mercury in air from 0.5 ng/m 3 within the overall possible range of me rcury concentration in ambient air.
Urban air pollution is a major environmental problem in the developing countries of the world. That`s why to monitor the air quality becomes fundamental to define the air pollution level and take important measures to improve the air quality.
Ahlstrom offers a high performance filter media for Air Quality Monitoring. A filter media made of extremely pure micro-quartz fibers, appropriate for emission control at high temperatures and wherever absolute purity of the filter medium is required.
To measure the air quality in a city is a challenge. A large number of gaseous components need to be measured with high accuracy. The monitoring site needs to be representative for the city and the system has to be easy to maintain and calibrate. The OPSIS open-path monitoring systems provide a flexible solution, giving the average concentration for an area. A single OPSIS system can measure all relevant gaseous components set by the authorities, such as NO, NO2, SO2, O3, BTX, NH3.
Car tunnels need ventilation in order to keep air pollution below the limits. When the pollution levels reaches a setpoint, the fans must be started and kept running until the pollution levels decreases.
Water pollution from airport run-off is increasingly coming under public and government scrutiny. As environmental regulations tighten, the ability to monitor for aviation fuel contamination from runway run-off has become essential.
Monitoring sites at airports can be extremely challenging often with no power or telephone lines available and with limited access for maintenance. Chelsea’s robust UviLux Hydrocarbon Sensor with its low power consumption and high accuracy is ideally suited for this application....
With the growth of contamination generated from agricultural and industrial production, it causes a threat to the enviroment including drinking water, atmosphere and soil. The chemists have always seeked out the effective analytical methods to detect and identify chemical contaminants. Dikma provides innovative products and application solutions according to government regulations and industry standards, for air and water quality monitoring, gas detection.
To test gas analyzers for Air Quality monitoring, gas references must have concentration in the range of hundreds to tenths ppb.
Test gas bottles with so small concentrations are expensive and unstable. With the gas divider BetaCAP30X100 it's possible to dilute high concentration test gases getting 30 dilution steps in the range from 1:100 to 1:3.000 of the original test gas bottle concentration.
Traditionally MFC based diluters are used for this application, but now our capillaries based diluter is available,...
The OPSIS open-path monitoring system is an excellent tool for monitoring the air quality, fugitive emissions and gas leaks at industrial sites. By arranging monitoring paths strategically at locations outside the borderline of an industrial area, fugitive emissions and gas leaks will effectively be detected. By combining the measured gas data with meteorological parameters information such as where the pollution sources are located and the strength of the emissions can be calculated, using the EnviMan software.

Requirements for monitoring emissions to air are governed by EU/UK legislation and are implemented in the form of a permit by the Environment Agency or local authority. The Dr Foedisch muti-component gas analysers continuously extract a gas sample from the exhaust stream via a stack probe into the analyser cabinet.
Both hot and cold gas systems are available, please contact us to discuss which system best suits your requirements.
Every day, wherever we go, we are exposed to minute amounts of environmental radiation.* This environmental radiation is emitted continuously, day and night, from various objects and substances in the natural world and our living environment.
Most environmental radiation consists of three types: alpha rays (α), beta rays (β) and gamma rays (γ). HORIBA`s PA-1000 `Radi` environmental radiation monitor makes it easy for non-specialists to measure even minute levels of gamma rays.
SO2 (sulfur dioxide) is measured in a number of applications. SO2 is used as a food grade preservative and must be regulated in accordance with government-set criteria to be safe for consumers. It is also measured in fuel exhaust to control for environmental pollution and in cement plants for process control.
Researchers and Engineers utilize HI-Q air sampling equipment and systems for analyzing and investigating environments around the world. Data collected by HI-Q air sampling systems have provided critical information in the identification and prevention of pollution. HI-Q offers a line of high volume (TSP-Type) air sampling systems for data collection in perimeter monitoring & industrial emissions monitoring applications.
With over 15 years of experience in the measurement of volatile organic compounds (VOC), Environment SA announces the VOC72M, a new generation analyzer for the measurement of BTEX compounds by gas chromatography with photo-ionization detector (PID). The VOC72M can handle up to 40 compounds and eight configurations for analysis. This compact and fully automated analyzer with wide voltage range specifications (90-240V) provides equivalent performance to the laboratory chromatographs and is particularly suited to...
From monitoring impurities in vents, stacks, air or water to point source or area monitoring, automatic and on-line measurement is an important tool. This type of measurement will detect, quantify and assist in reducing emissions. Siemens analytical products are utilized for many of these measurements.
The Series 8900 BTEX Analyzer provides direct measurement of Benzene, Toluene, Ethylbenzene, and Xylenes in ambient air. This instrument is utilized in ambient air networks around metropolitan areas and fence-line monitoring at industrial sites. The Series 8900 BTEX Analyzer employs a photoionization detector (PID) as the sensing element. This detector is specific to volatile organic compounds. The Benzene, Toluene, Ethylbenzene, and Xylene`s in the gas sample are physically separated using proprietary GC columns.
The real-time monitoring of odorous gases or more classical pollutants emitted by industrial sites (wastewater treatment plants, refineries, landfills, etc.) appears nowadays as a requirement, in order to optimize the site process and operations, or communicate towards the neighborhoods and local public bodies.
While emissions can be measured directly at the source (in the stack, exhaust, etc.), ambient air measurement all around the sites provides a better accuracy and anticipate pollution episodes. This is why...
The sustainability and environmental impact of a new build house is typically assessed using BREEAM. Part of the BREEAM assessment method is determining the air quality inside the house.
Gradko can supply a range of products for qualified BREEAM assessors. We try to work with qualified BREEAM assessors to determine and meet their requirements.
The products we normally supply are used for monitoring formaldehye and VOC levels in new build properties.
