  • 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 ...

  • Keeping Pace with PTP and CCRL

    Two, three or four times a year, laboratories around the world check their performance with testing programs from ASTM International’s Proficiency Testing Program and the Cement and Concrete Reference Laboratory. Using samples sent for a particular program cycle, labs run specific methods and submit their results to PTP and CCRL for analysis. Each lab then receives reports that serve as a ...
