    Ambient air quality monitoring solutions for 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....

    Continuous emissions monitoring for aluminium smelters

    Process control and emissions monitoring in an aluminium smelter is a challenge due to the high concentrations of HF. To use an extractive system in this environment will demand a lot of maintenance.

    Urban air quality monitoring

    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.

  • Gas Detection and Analysis Equipment for Chemical and Petrochemical

    In a complex petrochemical facility there may be many thousands of potential leaks paths. Some may be leaking but most will not. Using an infrared Gas Detection camera allows the user to examine many potential leaks sources in a short time and from a distance. The EPA acknowledged gas imaging cameras, such as Opgal’s EyeCGas®, as an approved Leak Detection and Repair (LDAR) Method 21 alternate work practice (AWP).

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

    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...

  • Portable Leak Detection

    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.

  • Measurement solution for CFC abatement control via two stream FTIR system

    CFC usage in industry

    Although the use of CFCs in domestic products has been widely phased out, CFCs chemicals still prove a vital ingredient in the production of insecticides and herbicides. Such products aim to increase the rate of crop production all over the world. All aspects of such a manufacturing process in relation to environmental impact must be well controlled. The use and pre-emission removal of CFCs in the intermediary steps of the insecticide production needs to be...
