Atomic Spectrometry Technology

An atomic spectrum is a spectrum consisting of a series of wavelengths of light emitted or absorbed by electrons in an atom as their energy changes. Atomic spectrometry technology is an analytical method that uses electromagnetic radiation or mass spectrometry to determine the elemental composition of a sample. Atomic spectroscopy technology mainly includes atomic emission spectroscopy (AES), atomic absorption spectroscopy (AAS) and atomic fluorescence spectroscopy (AFS). These technologies work on the principle that the wavelengths at which atoms absorb or emit energy are element-specific and therefore can be used to identify and quantify elemental composition. Atomic spectrometry technology is widely used in the environment, chemistry, geology, soil science, mining, metallurgy, food science and medicine.
