Atomic Absorption
GRAPHITE FURNACE ATOMIC ABSORPTION spectroscopy (GFAAS) is a type of spectrometry that uses a graphite-coated furnace to vaporize the sample. Briefly, the technique is based on the fact that free atoms will absorb light at frequencies or wavelengths characteristic of the element of interest (hence t... Read more
