(Main)Water quality - Determination of short-chain polychlorinated alkanes (SCCPs) in sediment, sewage sludge and suspended (particulate) matter - Method using gas chromatography-mass spectrometry (GC-MS) and electron capture negative ionization (ECNI) (ISO 18635:2016)
Water quality - Determination of short-chain polychlorinated alkanes (SCCPs) in sediment, sewage sludge and suspended (particulate) matter - Method using gas chromatography-mass spectrometry (GC-MS) and electron capture negative ionization (ECNI) (ISO 18635:2016)
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.
Wasserbeschaffenheit - Bestimmung kurzkettiger polychlorierter Alkane (SCCP) in Sediment, Klärschlamm und Schwebstoff - Gaschromatographisch-massenspektrometrisches Verfahren (GC-MS) unter Anwendung negativer chemischer Ionisation und Elektroneneinfang (ECNI) (ISO 18635:2016)
Diese Internationale Norm legt ein Verfahren zur quantitativen Bestimmung der Summe von kurzkettigen polychlorierten n-Alkanen fest. Diese werden auch als kurzkettige polychlorierte Paraffine (SCCP, en: short-chain polychlorinated paraffins) bezeichnet und haben Kohlenstoffkettenlängen von n-C10 bis einschließlich n-C13 in Gemischen mit Chlor-Massenanteilen („Gehalten“) zwischen 50 % und 67 %, die ungefähr 6 000 der etwa 8 000 Kongenere umfassen.
Dieses Verfahren ist anwendbar auf die Bestimmung der Summe von SCCP in Sediment, Schwebstoff, Klärschlamm und Boden mittels Gaschromatographie-Massenspektrometrie mit Elektroneneinfang nach negativer chemischer Ionisation (GC-ECNI-MS).
Abhängig von der Matrix und der Nachweisempfindlichkeit der GC-ECNI-MS kann das Verfahren auf Proben mit einer SCCP-Gesamtkonzentration von z. B. 0,03 µg/g bis 3 µg/g angewendet werden.
Qualité de l'eau - Détermination des alcanes polychlorés à chaîne courte dans les sédiments et matières en supsension (particules) - Méthode par chromatographie en phase gazeuse-spectrométrie de masse (CPG-SM) et ionisation chimique négative (ICN) (ISO 18635:2016)
L'ISO 18635:2016 spécifie une méthode de détermination quantitative de la somme de n-alcanes polychlorés à chaîne courte, également connus sous le nom de paraffines polychlorées à chaîne courte (SCCP), ayant une chaîne carbonée comprise entre n-C10 et n-C13 inclus, dans des mélanges dont la fraction massique («teneur») de chlore varie de 50 % et 67 %, englobant approximativement 6 000 des 8 000 congénères environ.
La présente méthode est applicable à la détermination de la somme des SCCP dans les sédiments et les matières en suspension (particules), les boues d'épuration et le sol, par chromatographie en phase gazeuse-spectrométrie de masse en mode d'ionisation négative par capture d'électrons (CG-INCE-SM).
Selon la matrice et les capabilités de détection de la CG-INCE-SM, la méthode peut être appliquée aux échantillons contenant, par exemple, de 0,03 µg/g à 3 µg/g de la somme des SCCP.
Kakovost vode - Določevanje polikloriranih alkanov s kratko verigo (SCCP) v sedimentu, blatu odpadnih vod in suspendiranih delcih - Metoda plinske kromatografije/masne spektrometrije (GC/MS) z negativno ionizacijo in zajemom elektronov (ECNI) (ISO 18635:2016)
Ta mednarodni standard določa metodo za kvantitativno določevanje vsote polikloriranih alkanov s kratko verigo (SCCP), znanih tudi kot poliklorirani parafini s kratko verigo, v razponu ogljikovih vezi n-C10 do vključno n-C13, v zmeseh z masnimi deleži klora (»vsebnost«) med 50 in 67 %, vključno s približno 6000 od približno 8000 analogov. Ta metoda se uporablja za določevanje vsote polikloriranih alkanov s kratko verigo v sedimentu ter suspendiranih delcih in zemlji z uporabo plinske kromatografije/masne spektrometrije (GC/MS) in negativno kemijsko ionizacijo z zajetjem elektronov (GC ECNI MS). Metodo je mogoče uporabiti za vzorce z vsoto polikloriranih alkanov npr. od 0,03 µg/g do 1 µg/g, odvisno od detekcijskih sposobnosti GC ECNI MS.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
