    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 ...
