  • CO2 vs. VOC Sensors for IAQ - What`s the Difference

    People sometimes ask about the differences between VOC (Volatile Organic Compounds) sensors and CO2 sensors. While both can be used to measure indoor air quality (IAQ), these sensors are not interchangeable. They measure very different things. CO2 sensing technology by IR (infrared) is stable and is not subject to the short-term, random drift found in air quality sensors. Most IR carbon ...

  • Monitor Volatile Organic Compounds (VOC’s) with PPM Technology’s IAQ Monitor

    Volatile organic compounds (VOC’s) are emitted as gases from certain solids or liquids. VOCs include a variety of chemicals, some of which may have short- and long-term adverse health effects. Concentrations of many VOCs are consistently higher indoors (up to ten times higher) than outdoors. VOC’s is one of numerous sensor options that can be incorporated into PPM Technology’s ...

  • Factors affecting the choice of VOC sensor

    VOCs (Volatile Organic Compounds) perform many vital roles as fuels, solvents, cleaners, feedstock, sterilants etc. However, they can be harmful to health and the environment, so it is often necessary to monitor their concentration. By definition, organic compounds contain the element carbon, and exhibit similar chemical properties, which is advantageous from a monitoring perspective. However, ...

  • Compressed breathing air safety - how important is it?

    At first glance the physiological demands of the firefighter, the scuba diver and the hospital patient have little in common. One is trained to deal with fire and rescue, one swims underwater and one is concerned with either regaining or improving their health. Yet all three depend to some extent on a safe source of compressed breathing air, which is where our gas detection systems come in. ...

  • The Role of Carbon Dioxide Detection in the Prevention of Sick Building Syndrome

    Sick building syndrome (SBS) is a medical condition where people, who work or live in the same building, suffer a variety of symptoms of illness and feel unwell, for seemingly no apparent reason. Common symptoms include eye irritation, headaches and shortness of breath. Typically, all of these symptoms are alleviated as soon as the sufferer leaves the building or room in question. While the exact ...

  • Is the solution to pollution dilution?

    Controls and monitors are part of environments where cleaning and purifying air moves beyond the usual HVAC filters and ventilation air. We can now utilize sensors and real time monitors that identify, track, and assure safe destruction of: mold, odors, allergens, bacteria, viruses, corrosion, chemical gases, and VOCs. Powerful proprietary filter media, adapted to each environment’s unique ...

  • TVOC used for monitoring toxic gases in laboratory environment

    The problem: dangerous leaks and contamination within laboratories Introduction Toxic gases can often be found in laboratories, due to the type of work that is done within a laboratory environment. Importantly, those responsible for working in laboratories are beginning to realise the implications and impact that toxic air-born substances can have on the health of the laboratory ...

  • Effects of high humidity on photoionisation detectors (PIDs)

    There are a few important issues to look out for when choosing an instrument. Like many sensors and measurement instrumentation, traditional PIDs can be affected by the adverse environmental conditions such as those found at fire scenes i.e. dirt, water and humidity. The situation in the immediate aftermath of a fire is therefore not ideal and in particular the presence of high humidity can ...

  • Offshore gas monitoring for health and safety

    Summary The need to maximise availability and to implement the most challenging of drilling plans, while all the time meeting stringent health and safety requirements, places immense pressures on offshore facilities managers. The costs of downtime and any subsequent clean-up due to an incident are unthinkable, and the costs of ill health are growing. Legislation demands the implementation of ...

  • Tech Note: Flare Gas Measurement Innovation; Retain Flow Metering Accuracy Even if Gas Composition Changes

    It’s a fact oil wells almost always produce natural gas along with the petroleum. Nine times out of ten, the excess gas (typically hydrocarbons) is flared off or simply vented as-is during upset conditions in the process. The environmental impacts of “flaring” this excess gas into our atmosphere has resulted in government regulations like 40 CFR Part 60 Subpart OOOO (also ...
