What is GFAA?

GFAA stands for Graphite Furnace Atomic Absorption Spectroscopy. It is a technique used in analytical chemistry to determine the concentration of an element in a sample. It involves using a graphite furnace to atomize the sample, followed by measuring the absorbance of light by the free atoms at a specific wavelength. This absorption is proportional to the concentration of the element in the sample. GFAA is commonly used for trace element analysis in environmental monitoring, food safety, and clinical chemistry.
