  • Analox case study: Monitoring oxygen at Cranfield airfield

    Introduction For personnel safety, monitoring of oxygen levels was required as part of an experimental field campaign based at Cranfield airfield. This experiment was undertaken by researchers in the atmospheric physics group at Imperial College London. The researchers are interested in measuring Far-infrared radiance fields in the atmosphere ...

  • Partitioning and Speciation of Trace Metal Diagenesis in Differing Depositional Environments in the Sediments of the Oman Margin

    Organic-rich sediment samples collected from a transect within, and below, the Oman Margin oxygen minimum zone (OMZ) were analysed using a sequential leaching technique to characterise the diagenetic behaviour and speciation of Mn and Fe in operationally defined sediment host fractions. Trace metals showed distinct diagenetic behaviour in the two contrasting environments that were sampled. The ...

  • Behaviour of Bulk and Trace Organics in a Full Scale Membrane Bioreactor for Landfill Leachate Treatment

    ABSTRACTLandfill leachates are generally highly pollutant wastewaters which have percolated through a deposit of solid waste. In many states it is now required to collect and treat landfill leachates to avoid contamination of surface and groundwater bodies. A state of the art technology for landfill leachate treatment uses membrane bioreactor technology prior to potential polishing with dense ...

  • Case study - Monitoring landfill gas

    Infrared absorption Infrared absorption is usually the preferred method for measuring methane and carbon dioxide. Most gases absorb radiation in the infrared region. The wavelength of radiation that is absorbed is determined by the natural vibration frequencies of the molecule. These natural frequencies will depend on several factors. Thus different gas molecules have different natural ...

  • 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 ...

  • Speciation of five arsenic compounds in urine by HPLC/ICP-MS

    High-performance liquid chromatography (HPLC) coupled to an ICP-MS has become an invaluable analytical tool for the determinations of trace levels of individual arsenic compounds (speciation). Speciation of arsenic is used to improve our knowledge of arsenic’s biochemical interactions and to evaluate toxicity risks. The toxicity and bioavailability of arsenic is highly dependent on form or ...

  • LIMS and the Automation of the Water Lab

    (Reproduced by permission from Laboratorium Magazine) Europe’s most modern water lab is located in Leeuwarden, in the Netherlands. Vitens made a big splash when it brought this modern building, with its transparent design, into operation in January 2005. Many colleagues from Dutch and foreign labs are eager to visit this installation, where water control samples are routed automatically with the ...

  • Why high temperature combustion of landfill gas?

    Due to the accumulation of knowledge and the tightening of environmental law, the landfill technology has increasingly become concerned with the management of trace compounds in landfill gas. With landfill gas, contamination is through sulphur, chlorine, fluorine, halogenated hydrocarbons and heavy metals. Other trace elements such as volatile organic compounds (VOC), impose environmental ...
