  • Laser gas detection is now cheap, fast and reliable

    Laser based gas detectors are now being used in a wide variety of applications for process and quality monitoring, and safety and environmental compliance. The reasons are that laser detectors are more reliable and less expensive than alternative solutions. Laser detectors combine semiconductor tunable diode lasers (TDL) and optical fibres developed by the telecommunications industry with ...

  • Gas detector communication technology for offshore oil and gas platforms

    In few applications is safety as important as on offshore oil and gas platforms. Explosive hazards from hydrocarbon gases and vapours are an ever-present risk, whilst toxic hydrogen sulphide gas and depleted oxygen environments can pose significant risks to personnel. Gas detectors are therefore essential to provide dependable early warning of gas hazards. Gas detectors are permanently installed ...

  • IR Gas Detector Provides Rapid Response

    The advanced Model IR400 Point IR Combustible Gas Detector from General Monitors features an industry-leading three-second T90 response time to the presence of combustible hydrocarbon-based gases, which allows plant operators to respond quickly to gas leaks and ...

  • 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 ...

  • 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 ...

  • A matter of degrees

    LumaSense Technologies’ E2T product manager, David Ducharme, explains why accurate temperature measurement is critical in a modified Claus sulphur reactor. There are two critical temperatures required for the safe and efficient operation of a sulphur furnace. The first is the refractory temperature, which is critical for hightemperature alarms and automated shutdown systems in the furnace. ...

  • 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: ...

  • What does `Corona` mean to you?

    If you heard the word 'Corona', what would you think of first? Beer? A crown? A solar corona? Maybe something else entirely? At Peak Scientific 'Corona' brings two things instantly to mind; Thermo Scientific's Corona Veo Charged Aerosol Detector, and the ...

  • Gas Detection in Recreation Facilities: Can the same detector work for pools and arenas?

    It is not uncommon for the same recreational facility to offer both skating and swimming amenities, two very different environments with different potential gas hazards. Given the fact that there is a possibility of 6 different types of gas to monitor and the large area between the two types of facilities, a single detector will not provide the monitoring requirements for both areas. It is ...

  • Improved HF monitoring in Primary Aluminium Smelters with Laser Gas Detectors

    Primary aluminium smelting generates large amounts of hydrogen fluoride gas (HF). Concerns for worker safety and ambient air quality require that HF be monitored at several locations in smelters. Historically, a variety of methods have been used for HF monitoring. Cassette samplers and wet chemistry techniques, coupled with complex and expensive ...

  • Detection and measurement of GWGs in semiconductor fab facilities

    Problem Statement Various processes and tools in the modern wafer fab plant produce effluent streams that contain unacceptably high levels of perfluorocarbon GWGs (greenhouse warming gases). These effluent streams are abated by plasma incineration and wet scrubbers and other techniques. It is necessary to measure the destruction removal efficiency (DRE) of the various abatement methods ...

  • Converting your GC carrier gas from helium to hydrogen : A step by step guide

    Learn how to convert your GC carrier gas from helium to hydrogen with this step by step guide. With recent increases in helium pricing and an increasing number of regulated methods allowing the use of hydrogen as a carrier gas for GC, ...

  • Gas safety in confined spaces

    An engineer repairs buried cables; a plant manager enters a small plant room; a contractor inspects the lining of a sewage pipe.  All these personnel face a common danger, despite working in widely different industries.  Gas-related injury poses a serious threat in any confined space where the free movement of air is limited.  ...

  • Stack gas VOC monitoring

    POLLUTION S.r.l. manufactures POLARIS FID analyzer, a cutting-edge technology for the measurement of total hydrocarbons in ambient air and stack emission monitoring in accordance with EN 13526 and EN 12619. This analyser is based on Flame Ionization Detection (FID), a reference method technique to measure total hydrocarbons (THC, VOC, TOC). Polaris FID is a very handy instrument because it allows ...

  • BTEX monitor, equal performances to laboratory chromatographs

    Environnement S.A leveraged its technical leadership in this field with an extensive experience, being one of the first companies creating its first BTEX analyser almost 20 years ago. The VOC72M third generation of ...

  • 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 ...

  • Building on a legacy of PID development

    Summary From the 1970s to the present day, photo-ionisation detectors (PIDs) have been at the front line of efforts to detect volatile organic compounds. As industrial hygiene has become ever more important and exposure limits for VOCs have reduced, PID technology has continued to develop, providing reliable detection under challenging environmental conditions at concentrations right down to ...

  • Development of on-line and field dual TD GC – MS for automatic VOC monitoring on petrochemical sites

    Ambient air is polluted by many semi-Volatile and Volatile Organic Compounds (SVOCs and VOCs) coming from anthropogenic and natural sources. VOCs from PAMS, TO14 and TO15 lists can be measured in many ranges of concentration, from pg/m3 up to mg/m3 depending on the location of the measurements. Due to the large number of molecules, the complete separation of all compounds is difficult to perform ...
