    Atomic absorption absorption spectroscopy (AAS) is one of the commonest instrumental methods
    for analyzing for metals and some metalloids. But because of interferences, poor reproducibility, and
    poor detection limits an alternative method for some elements--mostly metalloids--has been developed.
    Hydride generation atomic absorption spectroscopy (HGAAS) is available via an option for
    many modern AAS instruments. It "only" requires the hydride generation module.
