Water quality -- Determination of arsenic and antimony -- Part 2: Method using hydride generation atomic absorption spectrometry (HG-AAS)
Generally sea water is outside the scope of ISO 17378-2:2014. Sea water samples can be analysed using a standard additions approach providing that this is validated for the samples under test. The method is unlikely to detect organo-arsenic and organo-antimony compounds.
The sensitivity of this method is dependent on the selected operating conditions.
