Abstract
In this work different weight percent of copper and zinc powders of 20 ìm particle
size were blended carefully with grease , and the final weight of samples are 2 g . The
samples were placed in containers were made from tephlon of 2.5 cm as a diameter . The
bottom window of container was fitted with 6 ìm mylar film . The samples were
subjected to X- ray fluorescence to measure the Cu Ká and Zn Ká lines intensities .
Sensitivity (m) and Lower Limit Detection (LLD) were calculated and plotted against
the weight fraction for all samples .
