AES stands for which term?

• A. Anodic Stripping Voltometry
• B. Inductively Coupled Plasma Atomic Emissions Spectronomy
• C. Atomic Emission Spectronomy
• D. Environmental Leaf Proficiency Analytical Testing

Answer: (C)

Atomic Emission Spectrometry is a technique that determines what elements are present and how much of them there is by measuring the light emitted by atoms after they’re excited. In practice, a sample’s elements are energized (often with a flame or plasma). The excited atoms relax to lower energy levels and emit photons at characteristic wavelengths. A spectrometer separates these wavelengths and the intensity at each wavelength tells you the concentration of that element. When the excitation source is a plasma, this method is commonly called ICP‑AES or ICP‑OES, and the general term used for the method is Atomic Emission Spectrometry. Note that the standard spelling is Spectrometry, not Spectronomy. The other options describe different techniques or are not correctly named, so they don’t fit this concept.
