  • A quick guide to oil analysis for engine test applications

    Reliability testing is a very important component of new engine development. Engineers need to fully understand and chart the engine lifetime performance under a variety of conditions before mass production may be considered. Many important performance data parameters are collected in real time through the many different types of sensors that are connected to the engine in the test cell and oil ...

  • Influence of the Stirring Mechanism on the Precision of the Fusion for VITRIOX GAS and ELECTRIC

    Introduction Homogenization of the melt is an important aspect of sample preparation for X-ray fluorescence analysis using fusion. Whether the fused bead breaks or remains mechanically stable after cooling, depends largely on the homogenization. Once a stable fused bead has been obtained, it is only possible to judge if the sample is truly homogeneously dissolved in the flux by way of ...

  • Instrumental methods and challenges in quantifying

    Abstract Increased interest in the fate, transport and toxicity of polybrominated diphenyl ethers (PBDEs) over the past few years has led to a variety of studies reporting different methods of analysis for these persistent organic pollutants. Because PBDEs encompass a range of vapor pressures, molecular weights and degrees of bromine substitution, various analytical methods can lead to ...


  • Total solution: Gas and particulate analysis in Cement industry

    Cement plants are increasingly required to install continuous emission monitoring systems (CEMS). While these represent a significant financial outlay, a range of other factors also need to be considered when selecting a suitable CEMS. To the inexperienced, selecting a suitable CEM can mistakenly be considered as simply ensuring that the applicable national regulations (eg MACT in the USA, ...

  • Fire and Gas Protection Systems as Part of Safety Instrumented Systems and Risk Management

    Garth Watkins, Director Europe, Middle East, Africa, Detector Electronics Corporation, Presented at HazardEx International Conference 2008 Process-systems operators today face increasing demands for lower costs and higher safety standards in an increasingly regulated environment. In addition, companies desire to provide a working environment that is as safe as possible. As a result, plant owners ...

  • Gas cell selection for analysis of electronic gases

    APIMS and FTIR remain the preferred analytical tools for monitoring impurities in the electronic  specialty gases used by the semiconductor industry, although other tools such as CRDS are currently finding application in selected cases. FTIR spectroscopy offers the advantage of the simultaneous measurement of all gaseous species that exhibit dipole moment changes during vibrations at ...

  • Policy instruments and recent advances of the greenhouse gas regulating framework in shipping

    The development of a global framework for regulating GHG emissions from shipping is one of the most intensively discussed environmental topics in last decade. In general, shipping is considered an environmental friendly mode of transportation due to its energy-efficiency results. In July 2011 came a first mandatory global GHG reduction measure for the shipping industry. However, market-based ...

  • FTIR gas analysis improves container safety

    Introduction Entry to freight containers represents a significant hazard to staff responsible for inspection, stuffing or destuffing because of the large number of airborne chemicals that can be present. Research in Germany and the Netherlands found hazardous levels of gases and vapours in around 20% of all containers and this level of contamination is now accepted as commonplace. It ...

  • Mercury Analysis

    Characteristics of Mercury What is Mercury? Mercury is a naturally occurring silver-colored metallic element noted for its occurrence as a liquid at room temperature and toxic to living organisms. This silvery, opaque liquid metal is very dense, yet has a high surface tension that causes it to form tiny perfect spheres in the pores of the rocks it is found in. It is ...

  • Quantitative analysis of automotive exhaust gas by Fourier Transform Infrared spectroscopy

    For monitoring gaseous emissions from muffler, instruments presently used can only measure quantitatively a given pollutant. Fourier Transform Infrared (FTIR) spectroscopy can provide quantitative and online real time analysis. Calibration of our FTIR spectrometer with CO, CO2, NO, NO2 and N2O was done and the limits of quantification obtained were shown to be as low as 80 ppm. The variation ...

  • Accuracy and precision analysis of chamber-based nitrous oxide gas flux estimates

    Chamber-based estimates of soil-to-atmosphere nitrous oxide (N2O) gas flux tend to underestimate actual emission rates due to inherently nonlinear time series data. In theory, this limitation can be minimized by adjusting measurement conditions to reduce nonlinearity and/or by using flux-calculation (FC) schemes that account for the so-called 'chamber effect.' The current study utilizes gas ...

  • Low thermal mass gas chromatography – Analysis at MACH speed

    Gas Chromatography (GC and GC/MS) analysis has been the mainstay for the analysis of regulated organic contaminates in the environmental field. Numerous advancements have occurred in GC instrumentation that include improvements for injectors, detectors, automation, software, and GC column choices. Although many advancements have been made in GC technology, very little has changed for column oven ...


  • A multi‐attribute decision analysis for decommissioning offshore oil and gas platforms

    The 27 oil and gas platforms off the coast of southern California are reaching the end of their economic lives.
