  • Precise fertilizer management - Grass analysis by X-ray fluorescence spectrometry

    A significant proportion of agricultural land in Europe is grass for livestock grazing. For example, in the UK as a whole, the combined area of grassland is around 6,997,000 hectares, nearly 38% of the total agricultural area [2]. In NorthernIreland, where clay soils and a temperate climate are particularly suitable for grass production, this percentage is much higher. Here about 95% of farmland ...

  • X-ray fluorescence analysis of additives and wear metals in used lubricating oils

    The determination of metal concentrations in lubricating oils is a very important diagnostic development. Such analysis dates back over 50 years, when one of its earliest uses was to assess engine oil from trains. Today, the analysis of both new and used lubricating oils, as well as the monitoring of trends in the metal concentrations and additives they contain, has become an essential control. ...

  • Detecting Arsenic in Soil using Field Portable X-Ray Fluorescence

    Abstract Rapid, accurate on site determination of arsenic and heavy metal levels in soil is a powerful tool in efforts to rebuild and revitalize abandoned and under-utilized industrial properties. The EPA is actively spearheading initiatives to encourage assessment, clean-up and re-use of these industrial properties. In the case of heavy metals (often the eight RCRA metals Pb, As, Cd, ...

  • On the suitability of Portable X-Ray Fluorescence Analyzers for rapid screening of toxic

    Abstract X-Ray Fluorescence spectrometry (XRF) has been routinely used for alloy testing, determination of Pb in paint, and determination of Cd in plastic. However, its use to screen for toxic elements in food and medicinal products has been surprisingly limited to date. While XRF is less sensitive than atomic spectrometry methods such as ICP-AES and ICP-MS, it offers a number of significant ...

  • Comparing Field Portable X-Ray Fluorescence (XRF) To Laboratory Analysis Of Heavy Metals In Soil

    ABSTRACT Field portable x-ray fluorescence (XRF) continues to gain acceptance as a complement to traditional laboratory testing of metal contaminated soil. The quality of data produced by field XRF varies with site conditions, soil composition, and sample preparation. Quality assurance protocols for the field method usually require that a number of field samples be split and sent to a ...

  • Material History — The Past of Materials Read with X-Ray

    By using fluorescent X-ray, we can read out the past information hidden in a material. This lecture explained X-ray fluorescent analysis using synchrotron radiation by referring to the identification for the Wakayama Poisoned Curry Murder Case, presumption of origins of ceramic ware, and research on plants that absorb and accumulate toxic arsenic from the environment, as ...

  • X-ray analysis of tin solders aids RoHS/WEEE compliance

    The hottest topic in the electrical and electronic industry for some time has been the introduction of several directives with the same implications, the Chinese Administrative Measure on the Control of Pollution Caused by Electronic Information Products, the European Union (EU) and Japanese RoHS and WEEE directives. These regulations restrict the presence of lead, and other elements, in ...

  • Determination of the feasibility of using a portable x-ray fluorescence (XFR) analyzer in the field for measurement of lead content of sieved soil

    Soil samples collected in housing areas with potential lead contamination generally are analyzed with flame atomic absorption spectrometry (FAAS) or other laboratory methods. Previous work indicates that field-portable X-ray fluorescence (XRF) analysis is capable of detecting soil lead levels comparable to those detected by FAAS in samples sieved to less than 125 μm in a laboratory. A ...

  • Employing the Benefits of Atomic and Molecular Spectroscopy in a Combined X-ray Fluorescence/Raman Microanalyser

    X-ray fluorescence analysis (XRF) is a widely applied routine method for inorganic analysis of a variety of materials; compact ED-XRF equipment with microscopic analysis capabilities (μ-XRF) is available in different forms. Raman Spectroscopy (RS) is a highly specific method of molecular analysis that has shown it self to be admirably suitable for identification of many inorganic and organic ...
