Strontium analysis using Atomic Absorption Spectrophotometry (AAS) in both Flame and Graphite Furnace (GFA) modes is an advanced test used to determine the levels of strontium in samples such as water, soil, or biological tissues. Strontium is an important element from both an environmental and health perspective, as excessive exposure can have negative effects on the body. This technique offers high precision in measurements, helping researchers and scientists assess the potential risks associated with exposure to this element in various environments. The results are used in multiple fields, including environmental research, medicine, and various industries, to help make informed decisions about public safety and risk management.
