This International Standard specifies a method for the quantitative determination of the sum of shortchainpolychlorinated n-alkanes also known as short-chain polychlorinated paraffins (SCCPs) in thecarbon bond range, n-C10 to n-C13, inclusive in mixtures with chlorine mass fractions (“contents“)between 50 % and 67 %, including approximately 6 000 of approximately 8 000 congeners.This method is applicable to the determination of the sum of SCCPs in sediment and suspended(particulate) matter, sewage sludge, and soil using gas chromatography-mass spectrometry withelectron capture negative ionization (GC-ECNI-MS).Depending on matrix and the detection capabilities of the GC-ECNI-MS, the method can be applied tosamples containing, e.g. 0,03 μg/g to 3 μg/g sum of SCCPs.
