| Popis: | In this work Different weight of pure Copper,Nickel,Cobalt and Iron fine powders were blended carefully with engine Oil.X-ray fluorescence system was operated at 30KV and 17mA,the XRF intensities of Kα lines for all samples were measured at the peak and at background.The Lower Limit detection (LLD) and Sensitivity (m) of XRF Spectrometer were determined for different metal particles with different Concentrations (Wt%).The results of LLD and sensitivity of all suspended samples were plotted as a function of concentration , and the average values of LLD and m were calculated and plotted as a function of atomic number of metal particles suspended in engine oil. |
