Open Path Gas Monitoring Articles

Cerex Monitoring Solutions is pleased to announce the release of the third generation model AirSentry FTIR multi-gas open path FTIR analyzer. The decision was made to fully redesign the analyzer to take full advantage of advances in hardware and software technology. The third generation design represents a full reconfiguration of the instrument. Goals were to reduce initial and operating costs ...

The methods Open Innovation (OI) and Open Source Innovation (OSI) are often highlighted together as new forms of the creation of innovation. Their respective peculiarities are considered only rarely, because ? as Abdelkafi et al. argue in 2009 ? for many it suffices to say that both innovation methods imply an open participation of human resources. This is however not the case. By answering the ...

FTIR Spectroscopy is a widely used technique for gas analyses in industrial applications. It is a technique used in the semiconductor industry for measuring the purity of cleaning, etching, and epi-treatment gases used with various process tools, reactors, and abatement devices. Among chemical companies and R&D facilities, FTIR is applied to combustion thermodynamics and stack gas emissions; ...

Industrial change leading to industry convergence can be observed in many industries. This is provoked by the application of new technologies across industry boundaries, changing customer structures and regulations. Convergence presents a particular context for innovation and technology management, as firms face new bodies of technological and market knowledge which may create competence gaps. ...

One of the primary advantages of the Searchline Excel is its relatively high immunity to rain and fog. A field test conducted recently by BP and DMSI at the Texas A&M Fire School provided some further evidence of just how good Excel is at ignoring water in its optical path. The Fire School at Texas A&M University maintains a LNG test and training site that has long been equipped with Searchline ...

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 ...

How GasFinder works Boreal Laser’s GasFinder & GasFinder MC are open-path gas detectors that use an integrated transmitter/receiver unit and a remote, passive retro-reflector. In GasFinder (see below) the transceiver also houses the laser diode, drive electronics, detector module and micro-computer subsystems. The transceiver unit is contained in an IP65 enclosure and has connectors for power ...

This paper describes results from the first field experiment designed to evaluate a new approach for quantifying gaseous fugitive emissions of area air pollution sources. The approach combines path-integrated concentration data acquired with any path-integrated optical remote sensing (PI-ORS) technique and computed tomography (CT) technique. In this study, an ...
