AAS stands for which testing method?

• A. Atomic Absorption Spectroscopy
• B. Absorptive Analysis System
• C. Atomic Absorption System
• D. Absorption Spectroscopy

Answer: (A)

Atomic Absorption Spectroscopy is the method in question. In this technique, metal concentrations are determined by measuring how much light is absorbed by free atoms in the vapor phase after atomization (like in a flame or graphite furnace). Each element has specific wavelengths where its atoms absorb light, so the amount of absorption directly relates to how much of the element is present. This precise naming—Atomic Absorption Spectroscopy—is why it’s the correct choice. The other phrases aren’t correct because they don’t capture the specific technique. “Absorptive Analysis System” isn’t the established name for this method. “Atomic Absorption System” mutates the standard terminology and isn’t the conventional label. “Absorption Spectroscopy” is a broad field of techniques and doesn’t specify that the method uses atomic absorption for element quantification.
