Flame Atomic Absorption Spectroscopy

Flame Atomic Absorption Spectroscopy (FAAS) is an analytical technique used to measure the concentration of specific metal elements in a sample. The process involves converting the sample into free atoms by aspirating it into a flame, which atomizes the metals. A light beam with a wavelength specific to the element passes through the flame; only atoms of that element absorb light at that wavelength. By measuring how much light is absorbed, the instrument determines the amount of the element present. FAAS is widely used in environmental, clinical, and industrial analysis for its accuracy and ability to detect trace metal levels.
