  • Nanomaterials applied in medicine, cultural heritage and chemical sensor technology

    Herein, we report three different analytical applications of multi–layers of oxidised graphene nanoribbons (GNOs). In the first section of this paper, the most significant results concern the effect of GNOs on the proliferation of NIH3T3 murine fibroblasts. Results show that GNOs represent the most biocompatible nanomaterials (compared with other ones, such as carbon black, single–wall carbon ...

  • Safety Systems Depend on Reliable Field Sensors (Emphasis on Fire and Gas Detectors)

    Abstract Because not all hazards are the same, identifying and quantifying the hazard is the starting point in choosing sensing technology. Not all detectors are the same, and they should be selected according to their ability to detect the hazard. This paper gives a broad summary of technologies that provide users reliable responses to hazardous conditions, that minimise false ...

  • Developing Technologies to Detect Hydrogen Sulfide (H2S) Gas

    Abstract Hydrogen sulfi de (H2S) gas can cause nausea, headaches, unconsciousness, and death. Industries struggle to detect this deadly substance before it harms workers or communities. Safety system manufacturers have developed detectors that sense the H2S quickly and accurately. This paper illustrates, in general terms, considerations in effective placement of H2S detectors: ...

  • 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 ...

  • Not All Hazards are the Same: Design considerations for matching flame and gas hazards to detector technologies

    Not all flame and gas hazards in facilities are the same, therefore the detection technology chosen should be specific to the type of hazard to be detected. How do users select technologies to see certain fires or detect certain gases? The intent of this paper is to give a broad introduction to the selection and use of flame and gas detector technologies. We will answer questions such as these: ...

  • PureAire Makes Oxygen Monitor for Nitrogen Generators

    Nitrogen generators are most commonly used in areas where on-demand nitrogen is preferred rather than, storing liquid nitrogen (LN2) in cylinders.  Nitrogen generators have a lower cost of operation, and can be used where smaller amounts of nitrogen are needed. Nitrogen generators are used in the pharmaceutical industry, testing laboratories, cryogenic facilities, welding manufactures, and ...

  • Reliable pH measurement in Oily applications

    pH measurement in the petrochemical industry is frequently extremely difficult. Operating in high temperatures with highly reactive contaminants traditional pH reference electrodes can, in some applications, last only days. IC Controls 613 sensors reference is designed for difficult applications particularly where fouling or poisoning conditions exist. The reference uses a highly stable ...

  • Chlorine Dioxide gas detection: A comprehensive guide

    Introduction Some years agoago, the bleaching process in the paper industry was changed from using Chlorine (Cl2) as bleaching agent to Chlorine dioxide (ClO2). This was a challenge forThis posed a major challenge to industrial hygienists, as there were no sensors or detectors available that were specific to Chlorine dioxide: There was no sensor technology for gas detectors available that ...

  • Danger and Detection of Hydrogen Sulphide Gas in Oil and Gas Exploration and Production

    A rig worker smells rotten eggs near the well head, rubs his itchy eyes as he investigates the frosty pipe connections. After a few moments, he believes all is fine as he no longer smells the tell-tale hydrogen sulphide odour. In this scenario, we can only hope the worker recognises the danger and quickly leaves the site. Oil fields, especially mature ones, can produce hydrogen sulphide gas ...

  • Fixed Versus Portable Gas Detection – Which Is Better?

    Did you know that workers are needlessly injured every year as a result of leaking toxic or combustible substances? Such incidents are known to involve a wide range of hazardous gases (including ammonia, carbon monoxide, chlorine, hydrogen sulfide, hydrocarbon vapors and so on). The sad reality is that most of these accidents are avoidable if only the workplace is adequately monitored. This leads ...

  • Continuous emission monitoring and control of packed tower odor control systems using the sycamore CEM

    ABSTRACT Packed-tower chemical scrubbers, with sodium hydroxide (caustic) and sodium hypochlorite (bleach), are commonly used to treat foul air from wastewater treatment processes. The available control mechanisms include a pH probe and controller for the sodium hydroxide feed, an oxidation reduction potential (ORP) probe with a controller toestablish the bleach feed, and proprietary ...

  • Gas Monitoring for Ventilation Control and Energy Management

    The growing demand for underground and enclosed parking and maintenance garages (resulting from limitations on land availability) has increased the awareness and need for proper ventilation and control systems. In addition, increased health and safety programs have only added to the concerns of toxic and combustible gases in confined or enclosed spaces. Historically, ventilation and make-up air ...

  • 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 ...

  • Carbon monoxide v carbon dioxide – do you know the difference?

    In March 2015, we posted a blog about the American Red Cross getting confused between carbon dioxide (CO2) and carbon monoxide (CO) in a household initiative. A year later, we’d like to say that people have stopped getting their gases mixed up, but unfortunately this is not the case. ...

  • Oxygen Monitors for the New Millennium

    Oxygen monitors have become a required piece of safety equipment for many industrial and laboratory environments, where the release of certain toxics can create an area unsafe for living beings (human or animal).  When making a purchasing decision on any oxygen detection monitor, one need look no further than the sensor cell found at the heart of the monitor.  While each oxygen ...
