This paper represents an attempt to link different techniques such as laser and X-ray fluorescence (XRF). Where we used the laser in preparation and used X-rays to diagnose and analyze for non-traditional samples. The experimental procedure of the LSP is done by using a convergent lens to deliver 600 mJ (1064 nm) of energy and 10 ns laser pulse produced by Q-switched Nd:YAG laser of 1.5 mm spot size in diameter. Doubled distilled deionized water (DDDW) of 3 mm depth is used as transparent confining layer. X-Ray fluorescence technique used to analyze and determine the concentration of different nanoparticles suspended in motor oil. The results showed the accuracy in XRF measurements. the results of the motor oil analysis for Cu, Ni and Zn were 0.1225, 0.0480 and 0.000 weight percent respectively. Maximum relative error between actual measurements and XRF measurements were 6.5%, 10% and 12.5 for Cu, Ni and Zn nanoparticles respectively. The best percentage of suspension is 0.01 wt.%.
