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.

With the application of air quality PM2.5 standards, people have a clear understanding and attention on ambient air quality, countries also present clear requirements and control objectives. Due to the speeding up of development process of cities construction in recent years, unceasing expands of the urban area and population scale, sustained growth of energy demand, motor vehicle ownership, various construction projects, the situation of urban air quality improvement work is more severe.

New regulation forces ships to lower the emissions of SO2. Ships travelling in SECA areas has to either run on low sulphur fuel, or install SO2 scrubbers. To measure the SO2 emissions from a ship is not an easy task. OPSIS provides the Port Authorities with a unique measurement principle where the emissions from the ship is measured remotely. Light is passing the emissions and by analyzing the light, concentrations of SO2 can be measured.

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.

To monitor benzene emissions can be a challenge, but OPSIS makes it easy. Benzene is an aromatic hydrocarbon liquid that evaporates quickly if exposed to ambient air. It is one of the most commonly used substances in the chemical industry and it is known to cause cancer. For this reason, refineries in the United States must start monitoring fugitive emissions of benzene from January 30, 2018. This is part of the 2015 U.S. EPA Petroleum Refinery rule. In case a yearly rolling average of benzene concentrations...

Ambient air quality monitoring is the systematic, long-term assessment of pollutant levels by measuring the concentration and types of certain pollutants in the surrounding, outdoor air. Some of these pollutants (commonly called ‘Criteria Pollutants’) are considered hazardous to human health and their levels are regulated by government agencies around the world, including the US EPA. Teledyne API provides a complete line of ambient air quality monitoring instruments, including those for both gas and...

Primary aluminium smelting generates large amounts of hydrogen fluoride gas (HF). Worker safety and ambient air quality concerns require that HF be monitored at several locations in smelters. Traditionally, a variety of chemical sampling methods have been used for HF monitoring in and around smelters. However, these methods are labour intensive and require ongoing maintenance and consumables. During the past decade, laser based HF analyzers have been replacing the traditional methods. Laser analyzers are compact,...

Aerospace and aviation machining, welding, metal finishing, coating, and painting processes are complex and messy, often requiring clean rooms with precise temperature and humidity controls, as well as the need to isolate and capture contaminants via positive or negative pressure. But, expensive permanent enclosures aren’t efficient for alternating between short-term production projects and long-term constructions. What if you had a flexible clean air alternative that you could quickly deploy for existing...
