  • 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 ...

  • Upgrading from Pellistor Gas Sensors to Infrared Technology

    In this article Andy Avenell, Crowcon’s Fixed Systems Product Manager, considers the shift towards infrared (IR) gas sensor technology in the oil and gas industry. Abstract Flammable gases and vapours can present considerable dangers in many industrial applications, none more so than the processes involved in extracting, transporting and processing oil and gas. Fast and reliable ...

  • The Drumbeat on infrared thermal imaging

    Drumbeat Energy regards infrared (thermal) imaging as an amazingly useful tool in the quest for greater energy efficiency. It has the ability to define non-invasively and with uncanny speed and accuracy where heat is leaking from a building. Never was the expression “A picture paints a thousand words” ...

  • 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 ...

  • Biodiesel Analysis with Mid Infrared - From Feedstock to Fuel

    Introduction The biofuels industry is growing rapidly and so is the need for analysis to ensure quality product. The parameters for quality biodiesel require different types of instruments and measurement systems, such as gas chromatographs (GC), titrators, centrifuges, infrared spectrometers... Although claims are out there for the analyzer that will do it all, unfortunately there is no one ...

  • Solvent choices for infrared testing of oil and grease in water

    Water is a very strong absorber in the mi d infrared (I R) regio n where o il is measured. We see the effect of infrared absorbance when a cold bucket of water left in the sun is quite warm by afternoon due to the absorption of infrared energy as heat. When measuring part per million (ppm) oil levels with mid IR, the water absorbs so much of the infrared energy that the signal becomes saturated ...

  • The importance of background in the Detection and Identification of Gas Plumes using Emissive Infrared Hyperspectral Sensing

    Abstract Using a Fourier transform infrared field spectrometer, spectral infrared radiance measurements were made of several generated gas plumes against both a uniform sky and terrestrial background. Background temperature, spectral complexity, and physical homogeneity each influenced the success of emissive infrared spectral sensing technology in detecting and identifying the presence of a ...

  • High infrared emissivity coating for energy conservation and protection of inner surfaces in furnaces

    The appearance of some new furnace construction materials, e.g. ceramic fibre insulations and high emissivity coatings (such as "ENECOAT") [1,2] requires the revision of the traditional wall structures. Research was done regarding a silicon carbide based furnace coating. Its emissivity is considerably greater than that of the material onto which it was applied. The basic phenomena ...

  • A novel spectrometer design for process and handheld infrared spectral measurements

    Introduction Infrared spectroscopy offers many unique advantages for measurements within an industrial environment. Historically, the technique has been used for a broad range of applications from the composition of gas and liquid mixtures to the analysis of trace components for gas purity analysis. In cases where a well-defined method of analysis is involved, such as the measurement of ...

  • Comply with Highly Regulated Oil in Water Measurements Using Portable Infrared Analyzers

    The Petroleum Industry – both offshore and onshore -- has regulations that limit the amount of oil in discharged water.  Fixed filter infrared (IR) analyzers have been used to test oil levels in produced water on drilling platforms for over 45 years for a number of reasons. On oil rigs where real estate is at a premium, infrared analyzers such as the Wilks InfraCal TOG/TPH ...

  • Glass and glass-ceramics transparent from the visible range to the mid-infrared for night vision

    Many papers report studies on oxyfluorides glass-ceramics combining the optical advantage of fluoride environment for rare earth with the thermal and chemical advantages of oxide glasses [1?7], or on oxide-based glass-ceramics exhibiting exceptional thermo-mechanical properties such as zero thermal expansion coefficient. The transparency of these glass-ceramics is limited in the infrared region ...

  • Comparing TGA, FTIR and fixed filter infrared analyzers for measuring soot levels in in-service lubricants

    Measuring soot in diesel engine oil has become more important as soot levels get higher due to exhaust gas recirculation. As soot isone of the key indicators for the condition of the oil, diesel engine maintenance programs performing regular soot checks can realize cost savings by extending drain periods and reducing used oil disposal. TGA (Thermal Gravimetric Analysis) is the traditional method ...

  • Infrared spectroscopy of human bone marrow: evidence of structural changes during acute leukemia

    Fourier transform infrared (FTIR) spectroscopy was explored as a means to distinguish newly diagnosed of acute lymphoblastic leukemia from disease free bone marrow samples. Characteristic bands alterations were identified in both healthy and diseased samples arising from cellular protein, lipid and DNA. There were specific changes that affected the secondary structure of proteins that appeared in ...

  • Portable Infrared Analyzers Provide On-Site Measurement of Oil and Grease Levels in Hydraulic Fracturing Water

    The amount of water used in and produced by hydraulic fracturing of shale gas wells is in the millions of gallons per well.  Whether the water is going to be taken off-site for disposal or reused for re-injection, the flowback or produced water needs pretreatment to remove any residual oil from the water.  Waiting for remote laboratory results to determine the oil level can take several ...
