  • airmoTWA: New Expert System for GC-FID/MS

    Chromatotec has developed the first TRAP-GC-FID/MS designed for continuous monitoring of Volatile Organic Compounds (VOCs), inorganic molecules and permanent gases. In addition to the mass spectrometer (MS), this system encompasses the same trap, thermo desorption and separation technologies as airmoVOC analyzers (current mCERTS approved GCs analyzers). For VOCs analysis, the Flame Ionization ...

  • Detecting Gases: What You Can`t Smell Can Hurt You

    Walking through a drill-site area, a worker smells rotten eggs and stops tor a minute or two to assess where a gas leak might exist. Rubbing his itchv eves as he investigates further, he notices that he no longer smells the tell¬tale hydrogen sulphide odour. He does not realize that the gas has deadened his olfactory senses and unless he leaves the area within seconds, he could lose ...

  • Avoiding Sewer Fires with Vapor Space Organics Monitoring

    ABSTRACTRegulation of flammable gases released from wastewater discharges is facilitated by the use of the Vapor Space Organics test method. Such regulation can reduce the risk of a flash sewer fire, resulting damage and potential injury. The updated 2003 VSO process developed by Severn Trent Laboratories produced data that was equivalent to the 1990 VSO process developed and used by the ...

  • Selecting and Placing Gas Detectors for Maximum Application Protection

    Many industrial processes involve dangerous gases and vapors: flammable, toxic, or both. With the different sensing technologies available, and the wide range of industrial applications that exist, selecting the best sensor and locating them properly for the job at hand can be a challenge. To ensure a high level of safety, know the latest sensing technologies, which technology is best for the ...

  • A Regulatory Perspective on Maintenance of Disinfection Systems

    ABSTRACTThe Clean Water Act contains requirements to set water quality standards for all contaminants, including bacterial contaminants, in surface waters. Wastewater treatment cannot be expected to remove all of the bacterial contaminants, and as a result, many organisms remain in the waste stream. Therefore, disinfection of treated wastewaters is designed to reduce bacterial numbers to a safe ...

  • Upgrading from Pellistor Gas Sensors to Infrared Technology

    In this article Andy Avenell, Crowcon’s Fixed Systems Product Manager, considers the shift towards infrared (IR) gas sensor technology in the oil and gas industry. Abstract Flammable gases and vapours can present considerable dangers in many industrial applications, none more so than the processes involved in extracting, transporting and processing oil and gas. Fast and reliable ...

  • Is your Plant as tight as you think? Leak Detector for extremely toxic Gases, a Field Test Report

    Leak detection of commodity gases in chemical plants is a day-to-day practice. The sensor technology available for this application is field proven and reliable. No question about it, existing sensors will do the job. However, in plants manufacturing or handling extremely toxic substances, the picture is different. For example, take phosgene. The existing sensor technology for leak detection ...

  • Controlling Pharmaceutical Coating & Drying Process Emissions

    Capturing and destroying harmful emissions from pharmaceutical processes can be challenging. It’s not because the volatile organic compounds (VOCs) are difficult to destroy using catalytic or thermal techniques. It’s because their concentrations can be so high. These process streams raise safety concerns, both when they’re collected in vents and when they reach the final ...
