Spectral analysis is used for the precise determination of the chemical composition of metallic materials. With Optical Emission Spectrometry (OES) and X-ray Fluorescence Analysis (XRF), even the smallest alloying elements can be reliably detected. Atomic spectroscopy instruments can be divided into three basic types, depending on whether the phenomenon measured is based on light absorption, emission or fluorescence. Although atomic fluorescence can provide lower detection limits for some metal ions, these instruments are less commonly.
