| Abstract: | A high resolution (203 eV/Mn Kα) portable X-ray fluorescence spectrometer with 241Am as X-ray excitation source and Si-PIN as detector has been developed. A high performance application software with functions of automatic data acquisition, qualitative and quantitative analysis has been incorporated into the system. The instrument is small in size, light in weight, and portable. The long term stability of the system is satisfactory with a variation of 5% in 8 h. The detection limits of this system for most elements are one order of magnitude lower than the system with sealed proportional counter. Analytical applications of this system in rock and mineral analysis are also given. |
