ICP-OES is a spectroscopic technique used for the quantitative determination of the elemental composition of aqueous samples. Nearly all elements can be detected via ICP-OES with the notable exceptions being H, C, N, O, Ar, and halogens. Additionally, organic samples can also be analyzed using a specialized solvent and sample introduction system. Solid samples must be dissolved in water or acid digested prior to analysis. ICP-OES is a highly sensitive atomic spectroscopy technique able to provide limits of detection in the range of µg/L (10s of ppb) for most elements.
