ISO 12010:2012 水质.水中短链多氯代三苯烷类(SCCPs)的测定.使用气相色谱质谱分析法(GC-MS)和否定化学电离法(NCI)
Water quality - Determination of short-chain polychlorinated alkanes (SCCPs) in water - Method using gas chromatography-mass spectrometry (GC-MS) and negative-ion chemical ionization (NCI)
This International Standard 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 6300 of approximately 8000 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.
