graphite furnace atomic absorption spectrometry

Graphite Furnace Atomic Absorption Spectrometry

Atomic absorption spectrometry (AAS) enjoys excellent elemental selectivity and widespread usage with documented methodologies for a wide range of samples and matrices. Replacing the traditional flame atomizer with a graphite furnace (or 'electrothermal atomizer (ETA)') adds significantly to the flexibility of AAS and provides significantly lower detection limits.
