Zusammenfassung:	A technique facilitates formation evaluation with downhole devices which may include fluid analyzers having atomic absorption spectroscopy (AAS) systems. According to an embodiment, a fluid analyzer of a downhole tool may be positioned in a wellbore penetrating a subterranean formation. The downhole tool comprises a downhole flowline for receiving a sample fluid. Additionally, the fluid analyzer comprises a flowline positioned to receive the sample fluid for analysis by the atomic absorption spectroscopy system. The atomic absorption spectroscopy system has a light source to generate light and to excite atoms of a substance in the sample fluid. The atomic absorption spectroscopy system also comprises a detector to measure how much light has been absorbed by the substance, thus enabling the atomic absorption spectroscopy analysis.
