    Fence-line Monitoring

    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.

    Fence line monitoring around an industrial site or airport

    Monitoring the potential escape of pollutant gases from industrial sites or from airports can be difficult to achieve due to changing weather conditions, which may require a large number of monitoring stations downwind of the escapes.

  • Ambient Continuous Metals Monitoring/ Fence Line Monitoring/ Source Identification

    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 instrument in the industry.

    Emissions Monitoring for Mining / Emissions Monitoring for Smelting

    The Opsis monitoring solution for mining and smelting applications is based on either DOAS or laser diode technique. Opsis non-contact monitoring solutions are very well suited for applications in the Mining and Smelting Industries, as the flue gas conditions often involves high temperatures and high dust concentrations. The on-line, open-path systems are used for monitoring HF, sulphur dioxide, SO3 and HCl in potrooms, in fence-line applications and in continuous emissions monitoring.

    Measurement solution for on-line carbon bed system

    Commonly, activated carbon beds are used as abatement systems on plant, with emissions being reduced by adsorption onto the bed. The efficiency of any abatement system is critical to its operation, not just in ensuring emissions are reduced as much as possible, but an efficient bed has cost savings for the operator.

    Measuring aromatic hydrocarbons (BTEX) for pollution control and environmental monitoring

    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.

    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 of LpDNPH S10 cartridges and putting it in-line with the HPLC analysis will significantly reduce manual labor using this technique and this will improve reproducibility of the method by reducing potential experimental errors by the operator. The automation and unattended operation of the method leads to high throughput for determining airborne formaldehyde and acetaldehyde.

    Measurement of methane and non-methane hydrocarbons for environmental air quality.

    The Model 8900 Methane/Non-Methane Analyzer provides direct measurement of Methane and Non-Methane Hydrocarbons. This instrument is utilized in ambient air monitoring networks around metropolitan areas, fence-line monitoring at industrial plants and hazardous waste sites, and in the production of high purity industrial gases. Methane is a naturally occurring gas generated from the decomposition of biological materials and industrial activity. Since Methane is not considered a pollutant it is the Non-Methane hydrocarbons that are of primary concern.
