Soil quality - Determination of selected organotin compounds - Gas-chromatographic method (ISO 23161:2009)
ISO 23161:2009 specifies a gas-chromatographic method for the identification and quantification of organotin compounds (OTCs) in soils as specified in Table 1. The method is also applicable to samples from sediments, sludges and wastes (soil-like materials). The working range depends on the detection technique used and the amount of sample taken for analysis. The limit of quantification for each compound is about 10 µg/kg.
Organotin cations can only be determined in accordance with ISO 23161:2009 after derivatization. The anionic part bound to the organotin cation is mainly dependent on the chemical environment and is not determined using this method. The peralkylated organotin compounds behave in a completely different way from their parent compounds. Tetraalkylated organotin compounds which are already peralkylated, such as tetrabutyltin, are determined directly without derivatization.
Bodenbeschaffenheit - Bestimmung ausgewählter Organozinnverbindungen - Gaschromatographisches Verfahren (ISO 23161:2009)
Diese Internationale Norm legt ein gaschromatographisches Verfahren zur Identifizierung und Quantifizierung von Organozinnver¬bindungen (OZV) in Böden, wie in Tabelle 1 angegeben, fest. Das Verfahren ist ebenfalls auf Proben von Sedimenten, Schlämmen und Abfällen (bodenähnliche Materialien) anwendbar. Der Arbeitsbereich ist von dem angewendeten Nachweisverfahren und der für die Untersuchung genommenen Probemenge abhängig. Die Bestimmungsgrenze der Einzelverbindungen ist etwa 10 µg/kg.
ANMERKUNG Wenn dieses Verfahren zur Bestimmung von anderen, nicht in dem Anwendungsbereich festgelegten Organozinnverbindungen angewendet wird, sollte seine Eignung durch betriebsinterne Validierungsversuche geprüft werden, z. B. Methylzinnverbindungen (siehe Tabelle 2). Es ist unwahrscheinlich, dass Methylzinnkationen aus wässrigen Lösemitteln verdunsten, aber peralkylierte Methylzinnverbindungen sind flüchtig und neigen zu Verlusten (siehe C.3). Deshalb werden zusätzliche Vorsichtsmaßnahmen eingeführt.
Organozinnkationen können nach dieser Internationalen Norm nur nach der Derivatisierung bestimmt werden. Der an das Organozinnkation gebundene anionische Teil ist vor allem von dem chemischen Umfeld abhängig und wird mit diesem Verfahren nicht bestimmt. Die peralkylierten Organozinnverbindungen verhalten sich anders als ihre Ausgangsverbindungen. Tetraalkylierte Organozinnverbindungen, wie z. B. Tetrabutylzinn – die bereits peralkyliert sind – werden ohne Derivatisierung direkt bestimmt.
Die Eigenschaften, wie z. B. die Korngrößenverteilung, Wassergehalt, Gehalt an organischer Substanz der nach dieser Internationalen Norm zu untersuchenden Feststoffe, weichen weit voneinander ab. Die Probenvorbehandlung muss hinsichtlich der Eigenschaften sowohl der Organozinnverbindungen als auch der zu untersuchenden Matrix angemessen gestaltet werden.
Qualité du sol - Dosage d'une sélection de composés organostanniques - Méthode par chromatographie en phase gazeuse (ISO 23161:2009)
L'ISO 23161:2009 spécifie une méthode d'identification et de quantification des composés organostanniques (OTC) dans les sols. Cette méthode est également applicable aux échantillons de sédiments, de boues et de déchets (matières semblables au sol). La plage de travail dépend de la technique de détection utilisée et de la quantité d'échantillon prélevée pour l'analyse. La limite de quantification applicable à chaque composé est d'environ 10 µg/kg.
Les cations organostanniques peuvent être dosés conformément à l'ISO 23161:2009 uniquement après dérivation. La partie anionique liée au cation organostannique dépend principalement de l'environnement chimique et n'est pas déterminée par cette méthode. Les composés organostanniques peralkylés se comportent de manière totalement différente de leurs composés parents. Les composés organostanniques tétraalkylés comme le tétrabutylétain, qui sont déjà peralkylés, sont dosés directement, sans dérivation.
Kakovost tal - Določevanje izbranih organokositrovih spojin - Metoda plinske kromatografije (ISO 23161:2009)
Ta mednarodni standard določa metodo plinske kromatografije za ugotavljanje in kvantifikacijo organokositrovih spojin (OTC) v prsteh iz preglednice 1. Metoda se uporablja tudi za vzorce usedlin, blata in odpadkov (prsti podobnih materialov). Delovni razpon je odvisen od uporabljene tehnike za detekcijo in količine odvzetega vzorca za analizo. Meja kvantifikacije spojine znaša približno 10 μg/kg.

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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 23161 was prepared by Technical Committee ISO/TC 190, Soil quality, Subcommittee SC 3, Chemical
methods and soil characteristics.
