What Does FAS Stand For?

FAS stands for Flame Absorption Spectroscopy

Flame Absorption Spectroscopy (FAS) is an analytical technique used to determine the concentration of specific metallic elements in a sample by measuring the absorption of light at characteristic wavelengths. In this method, a sample is introduced into a flame, where it is atomized and excited, allowing the atoms to absorb light emitted by a radiation source. The amount of light absorbed correlates with the concentration of the element of interest, enabling precise quantitative analysis in various fields such as environmental monitoring, metallurgy, and food safety.
