ISO 17378-1:2014规定了砷和锑的测定方法。本方法适用于饮用水、地表水、地下水和雨水。ISO 17378-1:2014的线性应用范围为0,02μg/l至100μg/l。在适当稀释后，可分析浓度高于应用范围的砷或锑样品。 一般来说，海水不在ISO 17378-1:2014的范围内。可使用标准添加方法分析海水样品，前提是对试验样品进行了验证。该方法不太可能检测到有机砷化合物或有机锑化合物。 该方法的灵敏度取决于选定的操作条件。

ISO 17378-1:2014 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 ISO 17378-1:2014 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 ISO 17378-1:2014. 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 compounds or organo-antimony compounds. The sensitivity of this method is dependent on the selected operating conditions.
