Advantages of GFAAS (Graphite furnace atomic absorption spectrometry)

- Two orders of magnitude higher in terms of detection limit compared to ICP
- Very small sample sizes can be used
- Slurries and more crude samples can be analyzed by GFAAS - theses eliminates sample preparation time compared to ICP

Limitations of GFAAS

- GFAAS usually ...
