标准范围

ISO 25101:2009规定了使用高效液相色谱-串联质谱法（HPLC？MS/MS）测定饮用水、地下水和地表水（淡水和海水）未过滤样品中全氟辛酸盐（PFOS）和全氟辛酸盐（PFOA）线性异构体的方法。其他异构体可单独报告为非线性异构体，并作为非线性异构体进行鉴定。该方法适用于全氟辛烷磺酸的浓度范围为2,0 ng/l至10 000 ng/l，全氟辛烷磺酸的浓度范围为10 ng/l至10 000 ng/l。根据基质的不同，在适当稀释样品或减少样品量后，该方法也可适用于100 ng/l至200 000 ng/l的较高浓度。

ISO 25101:2009 specifies a method for the determination of the linear isomers of perfluorooctanesulfonate (PFOS) and perfluorooctanoate (PFOA) in unfiltered samples of drinking water, ground water and surface water (fresh water and sea water) using high-performance liquid chromatography-tandem mass spectrometry (HPLC？MS/MS). Other isomers may be reported separately as non-linear isomers and qualified as such. The method is applicable to a concentration range of 2,0 ng/l to 10 000 ng/l for PFOS and 10 ng/l to 10 000 ng/l for PFOA. Depending on the matrix, the method may also be applicable to higher concentrations ranging from 100 ng/l to 200 000 ng/l after suitable dilution of the sample or reduction in sample size.
