An Atomic Emission Spectrometer (AES) is an analytical instrument that identifies and quantifies elements in a sample by exciting them with intense heat (like plasma, flame, arc, or spark) to an unstable, higher energy state, causing them to emit light at unique wavelengths as they return to their ground state, with the emitted light analyzed to determine elemental composition and concentration. Key parts include a sample introducer (nebulizer), an excitation source (ICP is common), a monochromator to separate light, and a detector to measure intensity, offering simultaneous multi-element analysis for diverse applications.
