Energy-dispersive x-ray fluorescence (EDXRF) analysis has been established at the University of Dar es
Salaam, Faculty of Science, Department of Physics. Calibration was conducted using thin films from
Micromatter (USA) for secondary target XRF. We report on the performance of the spectrometer including
the detection limits attained, which range from 0.01 to 10 ng cm−2 using collimators of 6 and 8 mm diameter
under excitation conditions of 50 kV, 35 mA. The accuracy of the measurements was checked using IAEA
SOIL-7 and NIST 3087a Certified Reference Materials. The experimental values differed by <5% from the
certified values. The total reflection x-ray fluorescence (TXRF) facility added as a module to the existing
XRF system provides detection limits between 0.1 and 100 pg for most of the elements measured |
