Tunnel monitoring

by Opsis AB     based in Furulund, SWEDEN

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.

Simultaneous Air Monitoring over Multiple Fixed Sample Paths

by Boreal Laser Inc.     based in Edmonton, ALBERTA (CANADA)

Application: Simultaneous monitoring over multiple fixed sample paths either in-situ, extractive, or open path. Example: HF scrubber inlet, outlet, and stack monitoring in primary aluminum smelter.

Open Path Ambient Air Quality Monitoring

by Cerex Monitoring Solutions, LLC.     based in Atlanta, GEORGIA (US) (USA)

Cerex Multi-Gas Open Path Analyzers are available in both FTIR and UVDOAS technologies to meet specific requirements for perimeter ambient air quality monitoring, leak detection, fugitive emissions monitoring and ambient air quality monitoring.

Integrated real-time gas analysis solution for electronic specialty gases industry

by CIC Photonics, Inc.     based in Albuquerque, NEW MEXICO (USA)

The company’s entry into the electronic specialty gas market originated in 1994-95 as a consequence of the semiconductor industry’s demand for increasingly higher purity gases from the major gas producers. The issue was then and remains today to be primarily moisture impurity levels in the cleaning, etching, and treatment gases used in wafer production. In that earlier period when common wafer sizes were 6” and 12”, the semi industry required moisture concentrations to be 250 to 500 ppb or better; with each year after that the industry tightened its requirements such that today the moisture specifications are 1 to 5 ppb or better.

Single Gas Monitoring - Open Path Monitoring

by Boreal Laser Inc.     based in Edmonton, ALBERTA (CANADA)

Application: measurements of single gas species through a fixed open air sample path. Example: HF leak detection in refinery HF Alkylation units.

Portable Leak Detection

by Boreal Laser Inc.     based in Edmonton, ALBERTA (CANADA)

GasFinder2 can be used as a portable open path gas sensor to survey a large site relatively quickly. Areas of elevated gas concentration can be bracketed using shorter path lengths in order to locate leaking valves, flanges or fittings.

Fence-line Monitoring

by Opsis AB     based in Furulund, SWEDEN

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.

Urban air quality monitoring

by Opsis AB     based in Furulund, SWEDEN

To measure air quality in the ambient air is a challenge. The monitoring site needs to be representative and not dependant on changes in local traffic. A large number of gaseous components need to be measured with high accuracy and high availability.

Emissions Monitoring for Cars

by Boreal Laser Inc.     based in Edmonton, ALBERTA (CANADA)

GasFinderFC can be configured to monitor CO and CO2 simultaneously, and combined with the short open path probe, can be set up across roads to monitor instantaneous emissions of these gases from vehicles passing through the beam. Gross polluters can be identified and their number plates photographed.

Perimeter Ambient Air Monitoring

by Cerex Monitoring Solutions, LLC.     based in Atlanta, GEORGIA (US) (USA)

Cerex Multi-Gas Open Path Analyzers are available in both FTIR and UVDOAS technologies to meet specific requirements for perimeter ambient air quality monitoring, leak detection, fugitive emissions monitoring and ambient air quality monitoring. Cerex multi-gas analyzers offer significant advantages over single gas analyzer arrays, electro-chemical sensor arrays and time integrated air sampling hardware
