标准摘要
[中文适用范围]： ISO 17378的本部分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、雨水。 ISO 17378 这部分对于两种元素的近似线性应用范围为 0.5 µg/l 至 20 µg/l。 浓度高于应用范围的样品可以在适当稀释后进行分析。 一般来说，海水不属于 ISO 17378 本部分的范围。 海水样品可以使用标准添加方法进行分析，前提是该方法对受测样品进行了验证。 该方法不太可能检测有机砷和有机锑化合物。 该方法的灵敏度取决于所选的操作条件。 [外文原描述]： ISO 17378-2:2014 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 approximate linear application range of ISO 17378-2:2014 for both elements is from 0,5 µg/l to 20 µg/l. Samples containing higher concentrations than the application range can be analysed following appropriate dilution. 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.
