This document 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 
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 unfiltered surface water, ground 
water, drinking water and waste water using gas chromatography-mass spectrometry with electron 
capture negative ionization (GC-ECNI-MS).
Depending on the capability of the GC-ECNI-MS instrument, the concentration range of the method 
is from 0,1 µg/l or lower to 10 µg/l. Depending on the waste water matrix, the lowest detectable 
concentration is estimated to be > 0,1 µg/l. The data of the interlaboratory trial concerning this method 
are given in Annex I.
