Description (English):

ISO 18635:2016 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 sediment and suspended (particulate) matter, sewage sludge, and soil using gas chromatography-mass spectrometry with electron capture negative ionization (GC-ECNI-MS). Depending on matrix and the detection capabilities of the GC-ECNI-MS, the method can be applied to samples containing, e.g. 0,03 µg/g to 3 µg/g sum of SCCPs.

Abstract

Overview

EN ISO 18635:2016 specifies a validated analytical method for the quantitative determination of short‑chain polychlorinated alkanes (SCCPs) in solid environmental matrices. The method targets SCCPs in the carbon range n‑C10 to n‑C13 (technical mixtures with chlorine mass fractions between 50 % and 67 %, covering roughly 6 000 of ~8 000 congeners). It is designed for sediment, sewage sludge, suspended (particulate) matter and soil, and uses gas chromatography–mass spectrometry with electron capture negative ionization (GC‑ECNI‑MS / GC‑MS ECNI) for measurement.

Key topics and requirements

Analyte scope: Sum of SCCPs (C10–C13), independent of congener distribution or chlorine content.
Sample types: Sediment, suspended particulate matter, sewage sludge, and soil.
Analytical technique: GC‑MS with electron capture negative ionization (ECNI) for sensitive SCCP detection.
Sample preparation:
- Fortification with internal standard(s) prior to extraction.
- Extraction using pressurized liquid extraction (PLE) or equivalent.
- Sequential clean‑up (column chromatography and gel permeation chromatography, with alternative clean‑up options noted).
Calibration and quantification: Uses internal standardization and calibration approaches described in the standard (including multivariate calibration guidance in informative annexes).
Performance and detection range: Method applicability typically spans approximately 0.03 µg/g to 3 µg/g total SCCPs depending on matrix and instrument sensitivity.
Quality control: Normative procedures for QC, recoveries, chromatographic integration and reporting are included to support reliable routine use.

Applications

Routine environmental monitoring of SCCP contamination in sediments, sludges and suspended solids.
Regulatory compliance testing where SCCPs are listed or restricted (e.g., POPs monitoring and sediment quality assessments).
Site assessment and remediation verification for contaminated land and wastewater treatment residues.
Research studies on SCCP distribution, fate and transport in aquatic and terrestrial environments.
Supporting laboratory accreditation and method validation for SCCP analysis using GC‑ECNI‑MS.

EN ISO 18635:2016 is a practical, standardized procedure for laboratories performing SCCP analysis in solid matrices, providing clear requirements for extraction, clean‑up, GC‑ECNI‑MS measurement and quality assurance to ensure reproducible, regulatory‑grade data.
