  • Two Detector Solution to Analyzing Sulfur

    Sulfur compounds are reactive, corrosive to pipes, and destructive to catalysts in petroleum refineries. Sulfur emission are strictly regulated globally. When released into the atmosphere sulfur dioxide converts to sulfuric acid resulting in adverse effects on human health and the environment. Sulfur detection is found useful in many other industries; therefore, detection of sulfur compounds in ...

  • Metals Determination in Biodiesel (B100) by ICP-OES with Microwave Assisted Acid Digestion

    Elemental composition of biodiesel is required for product quality control, auto-engine life, emissions control, and researching appropriate additives. We studied the use of microwave assisted acid digestion reaction system to prepare neat biodiesel (B100) samples in an aqueous medium for ICP-OES analyses. Biodiesel produced by a transesterification reaction was subjected to the test method for ...


  • Best practices in identifying, reporting and screening operating experience at nuclear power plants

    Background Operating experience is a valuable source of information for learning and in the process improving the safety and reliability of nuclear power plants. One of the main elements of this process is the collection of event information in a systematic way that conforms with agreed reporting thresholds. The reported information than needs to be screened to ensure that all significant matters ...

  • Sample preparation for the analysis of matured timber

    The matured timber statute dedicates itself with the utilization and application of matured timber. A perfect assistant for the sample preparation are the FRITSCH Cutting Mills.  It especially includes rules concerning analysis for the examination of matured timber in regards to heavy metals (lead, cadmium, chromium etc.), arsenic, as well as PCP and PCB (pentachlorophenol and ...

  • Determination of micro and macro elements in waters with the ELAN DRC-e

    The ability of reaction cell technology to reduce the effects of spectral interferences is well-known, but another, lesser-known capability also exists: extending the dynamic range. This is accomplished by adjusting the bandpass parameters with no gas in the cell. Because the bandpass parameters can be adjusted on a per-mass basis, sensitivity can be reduced on selected isotopes without affecting ...

  • Innovations in Site Characterization. Case Study: Hanscom Air Force Base, Operable Unit 1 (Sites 1, 2, and 3)

     Executive Summary Field analytical instrumentation and methods were used to support a site characterization study at the Airfield at Hanscom Air Force Base (HAFB) Operable Unit 1. HAFB is located in Middlesex County, Massachusetts, and occupies land in the towns of Bedford, Concord, Lexington, and Lincoln. U.S. Air Force military operations began in 1941 and continued through 1973. With ...

  • BM Respirometry

    BM respirometery is a state of the art technology in where the traditional and most advanced respirometry techniques are gathered in one exclusive design developed by SURCIS Company. BM Respirometry makes use of a single reaction vessel that in certain mode replicates the actions that occur at a treatment plant under the conditions we set for the test. The BM system, under a powerful ...

  • Waste Rock Back Analysis

    On October 4, 2004, during field measurements collected in trench LFG-008, a crack developed in the middle of the trench. This occurred during the destruction of the Goat Hill North (GHN) rock pile at the Questa site. The crack varied in width up to a maximum of 100 mm and extended in an arc pattern around the pushed out section of the slope. The slope had been pushed in a convex arc out from the ...

  • Design and Analysis of a High Pressure Ratio Mixed Flow Compressor Stage

    I. Introduction Smaller frontal area and high thrust to weight ratios of mixed flow compressor stage has resulted in its application for small gas turbine engines in aviation sector [1] . The efficiency and reliability of the compressor depends to a great extent on flow behavior in its flow passage and its interaction between impeller and diffuser. The complex turning of the flow not only ...
