This part of ISO 17378 specifies a method for the determination of arsenic and antimony. The method is applicable to drinking water, surface water, ground water and rain water. The linear application range of this part of ISO 17378 is from 0,02 μg/l to 100 μg/l. Samples containing arsenic or antimony at higher concentrations than the application range can be analysed following appropriate dilution.
Generally sea water is outside the scope of this part of ISO 17378. 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 compounds or organo-antimony compounds.
The sensitivity of this method is dependent on the selected operating conditions.
