  • Fibre optic sensors as a non–destructive tool for structural monitoring

    Structural monitoring is a diagnostic tool for detection of defects/damages and for scheduling maintenance operations. It is essential to determine the safety of the structures by Non–Destructive Testing (NDT) for evaluation of strength/integrity. This assessment is required for the repair, rehabilitation and life extension of the structure. Fibre Optic Sensors (FOS) are attractive sensing ...

  • Reduced Emissions for Landfill Gas Installations

    The use of landfill gas as a source of renewable energy is increasing. For environmental and safety reasons, the owners of the waste storage sites have to strictly monitor and control the construction, operations, and emissions generated. Sulzer offers solutions to control these emissions within the limits given by the government. Landfill gas is similar to natural gas, but it is created by ...

  • Transforming Health & Safety

    What got us to where we are today will not get us to where we want to be tomorrow. Decades of awareness building, training, and record keeping on Occupational Health and Safety – spearheaded by private and public enterprises and prodded along by governments – have got us to where we are today. These efforts have moved us incrementally along a path over the past four decades from ...

  • Non–destructive radiotracer technique in characterisation of nuclear grade anion exchange resins Tulsion A–30 and Dowex 550A LC

    The present study deals with the application of non–destructive radio isotopic tracer technique to evaluate the performance of nuclear grade resins Tulsion A–30 and Dowex 550A LC. The evaluation was made by testing the performance of the two resins during iodide and bromide ion–isotopic exchange reactions. It was observed that at a constant temperature of 30°C, as the concentration of labelled ...

  • Effects of maturity on chlorophyll-related absorption in nectarines, measured by non-destructive time-resolved reflectance spectroscopy

    The ripening of fruits like nectarines and peaches is characterised by the decrease in chlorophyll content or colour of the fruit flesh. However, measuring the colour of fruit flesh is usually not conducted, as there is a lack of suitable techniques. Time-Resolved Reflectance Spectroscopy (TRS) is a novel technique that can measure the light absorbed by the fruit flesh. Using a laser light beam ...

  • Detection and measurement of toxic gases from destructive testing of batteries

    Problem Statement New formulations of organic-compound-based batteries for vehicle use must be tested for release of potentially harmful and toxic gases if crushed in accidents. Potential gases include hydrocarbons, fluorocarbons, and hydrogen fluoride, released within seconds of an incident. Actual time-resolved and quantitative data are required from destructive testing to ascertain ...

  • Cutting holes for testing vs. testing for holes

    When it comes to geomembrane quality assurance, are destructive testing practices as effective as basic leak detection technologies? The function of a geomembrane liner is to prevent liquid flow to the environment. CQA measures should be judged on how effective they are in meeting this requirement. This article critically examines the industry’s current means of providing confidence ...

  • Quality control put to the test

    X-RAY FLUORESCENCE spectroscopy (XRF) is ideal for quality control as it is non-destructive, requires simplesample preparation, and is very fast and accurate. Alternative techniques often require time-consuming, costly, andpotentially hazardous preparation before measurements can be made. The MiniPal QC is the latest addition to Panalytical’s successful line of MiniPal benchtop XRF ...

  • Hydrostatic Pressure Test

    A hydrostatic test is performed to determine the integrity and soundness of pressure vessels and piping joints. A decrease in the applied pressure or leakage through the products or joints or plastic deformation or distortion or bulging in the product is indication of inadequate quality of the product under test.   This test method is also termed as Leak testing (based on ...

  • Emission Testing of Engines to be Installed in Non-Road Mobile Machinery

    The European Commission has founded a project on emission testing – 'Emission Testing of Engines to be installed in Non-Road Mobile Machinery'. The project was undertaken by Abgasprüfstelle Berlin-Adlershof GmbH in Germany. The work is a part of emission inventory of spark-ignition engines to be used as a basis for a future amendment of the Directive 97/68/EC. The inventory covers seven different ...

  • Oil in frac water testing

    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 wa-ter. Waiting for remote laboratory results can take several days to a week. The InfraCal TOG/TPH ...

Whole Effluent Toxicity (WET) testing is an important component of the U.S. Environmental Protection Agency’s (USEPA’s) integrated approach for detecting and addressing toxicity in surface waters. The National Pollutant Discharge  Elimination System (NPDES) permit program, authorized by the Clean Water Act, controls water pollution by ...

  • Heat-enhanced bioremediation and destruction - Case Study

    Introduction In situ thermal treatment through Electrical Resistance Heating (ERH) is a proven robust technology for the treatment of volatile organic compound (VOC) source zones. ERH effectively treats the subsurface by volatilizing dense non-aqueous phase liquid (DNAPL) and VOCs, recovering the vapor, and treating the vapor by conventional technologies such as granular activated carbon ...

  • Assessment, Field Testing, and Conceptual Design for Managing Dense Non-Aqueous Phase Liquids (DNAPLs) at a Superfund Site

    AbstractDense non-aqueous phase liquids (DNAPL) greatly complicate groundwater remediation because the heavy DNAPL will sink and follow topographic lows within an aquifer system, and because DNAPL is difficult to extract using conventional pumping methods. These problems are now ...


  • Proficiency test of non-target screening with gas chromatography mass spectrometry to confirm a detected contamination of raw and drinking water

    Much of the water supply industry has implemented online monitoring and warning systems for chemical or biological contaminations. When a contamination is detected, further investigations are necessary to confirm or to cancel the initial alarm. The proficiency of a non-target screening approach with solid phase extraction and GCMS in full-scan mode was examined. A selection of pesticides and ...
