标准范围
ISO 12010:2012规定了一种定量测定短链多氯化氮总和的方法？烷烃，也称为短链多氯石蜡（SCCP），碳键范围为n-C10至n-C13（含），在氯质量分数（“含量”）在49%至67%之间的混合物中，包括约8 000种同系物中的约6 300种。该方法适用于使用电子捕获负电离气相色谱-质谱法（GC-ECNI-MS）测定未经过滤的地表水、地下水、饮用水和废水中短链氯化石蜡的总量。该方法可应用于含0.1 μ g/l至10 μ g/l的样品。根据废水基质，最低可检测浓度估计为>0.1 μ g/l。
ISO 12010:2012 specifies a method for the quantitative determination of the sum of short-chain polychlorinated n？alkanes, also known as short-chain polychlorinated paraffins (SCCPs), in the carbon bond range n-C10 to n-C13 inclusive, in mixtures with chlorine mass fractions ("contents") between 49 % and 67 %, including approximately 6 300 of approximately 8 000 congeners.This method is applicable to the determination of the sum of SCCPs in unfiltered surface water, ground water, drinking water and waste water using gas chromatography-mass spectrometry with electron capture negative ionization (GC-ECNI-MS).The method can be applied to samples containing 0,1 μg/l to 10 μg/l. Depending on the waste water matrix, the lowest detectable concentration is estimated to be >0,1 μg/l.
