AAS stands for which analysis technique?

• A. Atomic Absorption Spectronomy
• B. Advanced Absorption System
• C. Atomic Actuation System
• D. Analytical Absorption Sensor

Answer: (A)

Atomic Absorption Spectrometry is the technique represented by AAS. It measures how much light atoms in a sample absorb at specific wavelengths to determine metal concentrations. In practice, the sample is atomized in a flame or graphite furnace, and light from a lamp at the element’s characteristic wavelength passes through the vapor. The amount of light absorbed is proportional to the number of atoms, which you relate to concentration using a calibration curve. This method is especially useful for trace metals like lead in environmental samples. The other options aren’t standard analytical names for this technique. The term you’re looking for is Atomic Absorption Spectrometry (often spelled spectrometry).
