Practical Lecture on Atomic Absorption Spectroscopy
Dr. Minaa Abdul Salam Mustafa, a faculty member in the Department of Applied Chemistry at the College of Applied Sciences, University of Samarra, delivered a practical lecture on “Atomic Absorption Spectroscopy (AAS).” This technique is a vital analytical method used for accurately determining metallic elements in various samples.
The lecture provided a detailed explanation of the principle of atomic absorption and its mechanism in determining element concentrations. It also highlighted the importance of this technique in chemical, environmental, and industrial applications.
Dr. Mustafa explained the operation of the atomic absorption device and its main components, including the radiation source, burner, detector, and data analysis unit. The lecture also clarified the role of each part in analyzing metallic elements, methods of estimation using flame technology, and related applications, as well as graphite furnace technology for measuring trace concentrations.
The session concluded with a demonstration on sample preparation and analysis using the dedicated software for the atomic absorption device, along with interpretation of graphical readings and derived results.
