  • 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 ...

  • EDXRF Analysis of Sulfur and Other Elements in Oil

    The concentrations of sulfur substances in fuel oil, which greatly contribute to air pollution and acid rain, are regulated by law in many countries, and these regulations are becoming stricter with the growing concern about their impact on the environment and the consequences for society. Here, using the easy-to-operate EDX-720 energy dispersive X-ray fluorescence spectrometer, we determined the ...

  • Analysis of alternative fuels

    The use of alternative fuels in the cement and building materials industries is becoming increasingly important. Alternative fuels enable cement manufacturers to control production costs and improve environmental performance – two very significant benefits for one of the world’s most energy intensive industries. If international targets for the reduction of CO2 emissions are to be met, then the ...

  • Quantitative Analysis of Fluorine (9F) by EDXRF

      Fluorine compounds possess a wide range of properties, including flame retardance, water repellency, anti-fouling property, and heat resistance, and are therefore used in a wide range of fields from articles for everyday use to semiconductors. However, since the 1980s, the problems of global warming and ozone depletion in addition to the potential for bioaccumulation have led to ...

  • X-ray slag monitoring

    According to market research published by the Freedonia Group in June 2006, global demand for cement is forecast to ‘grow to 4.7 per cent yearly through 2010’. While demand for Portland cement, which currently accounts for three-quarters of all cement sales worldwide, will be healthy, sales of blended cements are expected to climb at a faster pace. Similarly, the Slag Cement Association reports a ...
