  • A Comparison of Point Sensors and Open Path Monitors For Toxic Gas (esp. HF) Monitoring

    Point Sensors Ion Mobility Spectroscope (IMS) – a gas sample is ionized by a radioactive source (Ni63). Differences in ion drift under the influence of an applied electric field produce a spectrum that is dependent on the mass, charge, and shape of the component ions. The detector signal and strength is tuned to the drift time of the ion of interest (in this case HF) and signal strength is ...

  • Retail Store, Loganville, GA

    Prior to EXO TECIfs involvement. extensive soil excavation was performed of the former gasoline UST pits followed by an unsuccessful injection using only hydrogen peroxide. EXO TECH was then contracted and mobilized to the site and installed additional injection wells and performed three small dose injections using persulfate activated with hydrogen peroxide. Due to preferential ...

  • Advanced gas analysis - on the go

    The field of ambient air analysis - monitoring industrial and other environments for harmful concentrations of gases - has traditionally faced a technology limitations: Would you prefer a complete and reliable tool, which will be bulky, complicated and inconvenient? Or would you like a nice portable one that's simple and lightweight, but unreliable and limited in its capability? Truly complete ...

  • What’s the big deal about ion mobility mass spectrometry?

    Ion mobility spectrometry (IMS) is a technique that differentiates ions based on their size, shape, charge, and mass. While often used in small, portable devices at airports and remote locations for rapidly detecting small molecules whose mobility is known (for example, certain narcotics and explosives) when coupled with liquid chromatography-mass spectrometry (LC/MS), IMS provides an orthogonal ...

  • Landfill gas explosive for global warming

    In response to EPA’s 1991 landfill rules that pushed the industry to larger facilities, landfill operator’s today pile and compact trash on the ground into giant mounds in the shape of a four sided pyramid. As originally contemplated, these mounds of trash were encased in liners to keep the wastes dry so contaminants would not be mobilized to leak into groundwater, along with ...


  • Oil & Gas Leakage Detection Contractors

    RADS (Remote Aerial Detection Systems) teamed with market leading vendors to supply state-of-the-art Intelligence Surveillance and Reconnaissance (ISR) and security equipment. RADS is a US-based top-tier Technology Integrator that serves international commercial and government customers across the world. Unlike the large US defense contractors, RADS is independent and can operate with agility ...


  • Monitoring greenhouse gases from biofuel crops

    Global issues such as climate change and energy security have driven rapid growth in renewable energy production - wind, solar, tidal, geothermal, hydro, biofuels etc. However, logically, each of these methods should deliver a net benefit in terms of greenhouse gas (GHG) reduction, so researchers in the United States have employed portable FTIR analysers to study the GHG emissions of biomass ...

  • Workplace Monitoring: Who, What, When, Why, How?

    In my previous articles in this series for SHP readers, I have focussed on the need for current attitudes to general health and safety processes to change and emphasised the importance of regular monitoring. The best way to combat those ‘hidden killers’ and protect our workforces is to increase awareness of the benefits of regular monitoring and detection.  Employees then need to ...

  • The challenges and benefits of local air quality monitoring

    A new generation of air quality monitors is now being offered to provide localised, real-time air quality readings – but the potential benefit is only just starting to be realised. It is generally accepted that whilst measurements from air quality reference stations are highly accurate, they are not sufficiently location-specific. Key pollutants – such as NO2 and PM2.5 ...

  • Gas analysers support management of Swindon fire

    The capability to convene a multi-agency Air Quality Cell (AQC) was established in England in 2009 following the Buncefield Oil Storage Depot incident. A review of this event identified the need to rapidly co-ordinate the acquisition, analysis and interpretation of air quality data in major incidents. Arrangements have been made in England to bring together experts from the Environment Agency ...

  • Increased Demand for PureAire’s Oxygen Monitor for Nitrogen and Helium Storage

    When storing or using Liquid Nitrogen, Helium, CO2, or Argon cylinders in a confined space, what are the potential risks? Gas leaks are the most common, requiring the need for an oxygen deficiency monitor for protecting employees in the workplace.  With inert cryogenic gases, loose or broken fittings can leak gas into a room displacing oxygen, causing impaired judgment or loss of life to ...

  • Fast, simultaneous and continuous monitoring of NOx and NH3 in DeNOx applications

    In DeNOx systems using urea injection with ammonia (NH3) as a reducing agent, the flow rate and control of NH3 must be continuously adjusted and controlled to prevent excess NH3 emissions (slip), to reduce environmental impact and cost of reagents. To optimize this process, it is essential to use an emissions analysis system for simultaneous and continuous monitoring of NOx and NH3. For preparing ...
