Introduction
Short-chain chlorinated paraffins (SCCPs) are a mixture of chlorinated hydrocarbons with a chain
length of 10 to 13 carbon atoms and a chlorine content of 40 % to 70 %. SCCPs are classified as
dangerous to the environment, since they are very toxic to aquatic organisms and can cause long-term
adverse effects in the aquatic environment.
In 2002, the European Directive 2002/45/EC restricted the sale and use of SCCPs (C to C ) in product
10 13
preparations for the fatliquoring of leather. Preparations containing concentrations equal to or higher
than 1 % of SCCPs were forbidden. This directive is included as part of the EU Regulation 1907/2006
(REACH). Within this EU Regulation, in October 2008, the SCCPs were added to the candidate list of
[2]
substances of very high concern (SVHC) .
[3]
The EU Commission Regulation 2015/2030 in November 2015 prohibited alkanes C to C , chloro
10 13
(SCCPs) (CAS No 85535-84-8), as constituents of articles. Articles containing SCCPs in concentrations
lower than 0,15 % by mass are allowed.
In 2017, the SCCPs were listed in Annex A of the Stockholm Convention on Persistent Organic Pollutants
[4]
(POP) .
The analysis of chlorinated paraffins is a challenge. The technical compounds are mixtures of up to
200 congeners with different chain lengths and degrees of chlorination. GC chromatograms of these
complex mixtures typically show a lot of overlapping peaks that can be difficult to separate. In
particular, the responses to the various chlorination degrees can vary over a large range.
In addition, the presence of sulfochlorinated paraffins and equivalent chain-length chloroalkenes in
such technical compounds can cause interference.
This document describes a procedure to compare the chromatogram results for SCCPs compounds from
a test sample with the chromatogram results of a defined calibration standard of the most typically
used mixture (59 % chlorination for SCCPs). With this gas chromatography negative ion chemical
ionization mass spectrometry (GC-ECNI-MS) procedure it uses four ion traces for identifying the SCCPs.

Introduction
Short-chain chlorinated paraffins (SCCPs) are a mixture of chlorinated hydrocarbons with a chain
length of 10 to 13 carbon atoms and a chlorine content of 40 % to 70 %. SCCPs are classified as
dangerous to the environment, since they are very toxic to aquatic organisms and can cause long-term
adverse effects in the aquatic environment.
In 2002, the European Directive 2002/45/EC restricted the sale and use of SCCPs (C to C ) in product
10 13
preparations for the fatliquoring of leather. Preparations containing concentrations equal to or higher
than 1 % of SCCPs were forbidden. This directive is included as part of the EU Regulation 1907/2006
(REACH). Within this EU Regulation, in October 2008, the SCCPs were added to the candidate list of
[2]
substances of very high concern (SVHC) .
[3]
The EU Commission Regulation 2015/2030 in November 2015 prohibited alkanes C to C , chloro
10 13
(SCCPs) (CAS No 85535-84-8), as constituents of articles. Articles containing SCCPs in concentrations
lower than 0,15 % by mass are allowed.
In 2017, the SCCPs were listed in Annex A of the Stockholm Convention on Persistent Organic Pollutants
[4]
(POP) .
The analysis of chlorinated paraffins is a challenge. The technical compounds are mixtures of up to
200 congeners with different chain lengths and degrees of chlorination. GC chromatograms of these
complex mixtures typically show a lot of overlapping peaks that can be difficult to separate. In
particular, the responses to the various chlorination degrees can vary over a large range.
In addition, the presence of sulfochlorinated paraffins and equivalent chain-length chloroalkenes in
such technical compounds can cause interference.
This document describes a procedure to compare the chromatogram results for SCCPs compounds from
a test sample with the chromatogram results of a defined calibration standard of the most typically
used mixture (59 % chlorination for SCCPs). With this gas chromatography negative ion chemical
ionization mass spectrometry (GC-ECNI-MS) procedure it uses four ion traces for identifying the SCCPs.
