Atomic Fluorescence Spectroscopy (AFS)
Atomic Fluorescence Spectroscopy (AFS) is an analytical technique used for the detection and quantification of metallic elements in various samples. It is particularly useful for measuring trace levels of toxic heavy metals in environmental, food, and biomedical samples.
In AFS, the sample is first converted into an atomic gas using an ionization method, such as exposure to a flame or other heat source. The atomic gas is then exposed to visible or ultraviolet light of a specific wavelength, which causes atoms of a specific element to fluoresce. The fluorescence emitted by these atoms is then detected and measured, allowing for the determination of the concentration of that particular element in the sample.
