  • Analytik Jena AG: State of the Art - Fully Automated and Matrix-Optimized Gas Analysis with multi EA 5000

    The analysis of gaseous matrices is still a real challenge. No matrix type is as versatile in its behavior and the requirements for sample feed and combustion process. This makes it difficult to gain quick, precise, and reliable results. Thanks to the outstanding flexibility of the application-optimized gas sampling systems, the elemental analyzer multi EA 5000 can analyze liquefied gases (LPG), ...

  • Plastic Housewraps (Air Barriers) a Life Cycle Analysis of Their Environmental Benefits

    The use of air barriers in the construction of residential housing in North America has increased markedly during the last decade. The most commonly used air barriers have been particular plastic materials applied to the exterior of a home behind the finishing of brick or siding. The paper analyses, using life cycle techniques, the conservation of energy resulting from the use of these barriers ...


  • Rapid HPLC Analysis of PAH Compounds, Using Porous 3µm Particles

    Polynuclear aromatic hydrocarbons (PAHs) are a severe environmental hazard with a variety of sources. Airborne particles, combustion products, and fossil fuels all contain these toxic aromatic substances. Analysis by gas chromatography (GC) has been problematic because GC phases do not meet the need for shape selectivity in separating PAHs. Conversely, high-density C18 octadecylsilane (ODS) ...

  • Second-law analysis of an LPG-powered 4-stroke SI engine under variable stroke length and compression ratio

    A second-law analysis of an LPG-powered, 4-stroke, single-cylinder, water-cooled, variable stroke length spark-ignition engine was carried out to assess the engine's energy efficiency. The engine was simulated at each stroke length/compression ratio combination. The second law of thermodynamics with the aid of the first law represents the results of entropy generation, reversible work output and ...
