This market is driven by law and legislations made in Europe and/or USA (US EPA). It deals with ambient air monitoring : analysis / calibration / automatic zero air in continuous 7 days a week. Ambient air monitoring: in France this service is controlled by associations that calculate the ATMO index. CHROMATOTEC instruments such as the BTX ,the Sulfur and the VOC analyzers can be a good complement of their analyzers such as O3, CO2, DUST… in the analysis of ambient air.
The Xact® 625i combined with ADAPT software creates the industry`s most powerful tool for high time resolution detection of airborne metals. The Xact® 625i measures trace metals at very low detection limits at time resolutions down to 15 minutes. The ADAPT package captures corresponding wind speed and wind direction data, then seamlessly integrates the measurements into wind regression analyses available at the touch of a button. This creates the most single most powerful fence line/ source identification...
According to US EPA IO - 3.3 standard method of heavy metals, flue gas heavy metals analyzer uses XRF nondestructive testing technology and flue gas automatic enrichment technology to realize the accurate measurement of flue gas heavy metals such as waste incineration plants, cement plants, thermal power plants, etc.
Continuous monitoring of HF concentration in aluminum smelters is a key issue for optimization of aluminum production. Continuous gas analyzers support the steel industry by helping facilities optimize processes and reduce expenses.
SO2 is one of several important pollutants in the atmosphere, SO2 from the atmosphere can stimulate people`s respiratory tract, abate respiratory function, and lead to respiratory resistance decreased, induce various inflammation of respiratory tract, harm to human health. SO2 also is harm to many plants. SO2 and its generated sulfuric acid mist can corrode metal surfaces and cause damage to paper products, textiles, leather products. It may also form acid rain, which is serious harm to the ecological system and...
The Opsis monitoring solution in aluminium smelters is based on either DOAS or laser diode technique. The on-line, open-path systems are used for monitoring HF and sulphur dioxide in potrooms, in fence-line applications and in continuous emissions monitoring. Opsis has long experience of monitoring in aluminium smelters.
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 nature of steel manufacturing processes places severe limitations on the monitoring methods that can be used. Aggressive environments combined with high levels of particulates and gases make the choice very limited.
Steel mills include a multitude of activities that generate gaseous emissions. Besides continuous emissions stack monitoring, the applications in a steel mill also include process mesaurements that provides important data to the operators in order to optimize the steel making process.
Phosgene COCl2 is a colorless gas. While it has been used as a Chemical Weapon Agent (CWA) in the past, currently this poisonous gas is also an important reagent in synthesis in the pharmaceutical and chemical industries. The plants using phosgene are typically equipped with gas sensors to detect leaks in the indoor ambient air. The critical situations arise when equipment in contact with the gas at the manufacturing facilities are serviced and maintained. As phosgene is very poisonous, even small gas pockets in...
Cooper Environmental`s Xact® 640 has the unique ability to generate high time resolution metals measurement in stacks. This unique capability has the potential to qualify as a substitution for the combination of a Hg/ PM CEMs application as well as the potential for a pollution control system feedback loop that could result in the reduction of pollution control consumables. Our systems have been site certified for compliance measurements at hazardous waste incinerator and secondary lead smelter sites.
To monitor H2S can be difficult. The UV absorption is without structure and the IR absorption has strong interference from H2O. The traditional way has been to remove all SO2 from the sample while keeping H2S, then convert H2S to SO2 ,and finally measure SO2 which then effectively yields the H2S concentration. The instruments used have often been ambient air SO2 analysers and extractive dilution systems. However, it is not unusual to experience practical problems with these type of installations.
The Series 8900 Hydrogen Sulfide and Carbon Disulfide Analyzer provides direct measurement of H2S and CS2 in ambient air. This instrument is utilized for continuous emission monitoring. The Series 8900 H2S and CS2 Analyzer employs a Photoionization detector (PID) as the sensing element. A dual column configuration with timed backflush to vent is used to strip off moisture and heavier hydrocarbons. A pre-cut column is used in series with the analytical column. At sample injection a fixed volume of sample is...
Fugitive emissions can be a health concern during removal and disposal of mercury-contaminated material at remediation sites. Thus, remediation projects either indoors or outdoors often require on-site, real-time mercury air monitoring with a Tekran 2537. This assures permitted levels are not exceeded during waste processing and human exposure levels are below government regulated toxicity thresholds. Often multiple sites must be monitored continuously. The Tekran 1115 Multi-Port Sampler is the ideal tool for...
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.
Customized solutions – from development to customer service! The carbon dust required for the production of steel can be continuously measured directly in the conveyor lance by specially developed measuring systems of ENVEA - SWR. With this technique thermal imbalances in blast furnace can be avoided, and it can be directly reacted to production stops.
The construction of coal and natural gas power stations is continuing at a steady rate along with older power stations being retrofitted with more effective flue gas cleaning systems. Both the community and environmental protection authorities are paying closer attention to both emission and ambient concentrations around power stations.
Gradko’s ambient air monitoring equipment is widely used to monitor both indoor and outdoor air quality. Continuous development allows us to provide equipment for a broad range of applications, covering short-term and long-term monitoring. Pollutants can be detected even at very low levels – limits of detection are typically in the low parts per billion (ppb) range.
