Soil quality - Determination of selected organotin compounds - Gas-chromatographic method (ISO 23161:2018)
This document specifies a gas-chromatographic method for the identification and quantification of organotin compounds (OTCs) in soils as specified in Table 1.
This document 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.
Bodenbeschaffenheit - Bestimmung ausgewählter Organozinnverbindungen - Gaschromatographisches Verfahren (ISO 23161:2018)
Dieses Dokument legt ein Verfahren zur gaschromatographischen Identifizierung und Quantifizierung von Organozinnverbindungen (OZVs) in Böden, wie in Tabelle 1 angegeben, fest.
Dieses Dokument 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.
Qualité du sol - Dosage d'une sélection de composés organostanniques - Méthode par chromatographie en phase gazeuse (ISO 23161:2018)
Le présent document spécifie une méthode d'identification et de quantification des composés organostanniques (OTC) dans les sols comme spécifié dans le Tableau 1.
Le présent document 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.
Kakovost tal - Določevanje izbranih organokositrovih spojin - Metoda plinske kromatografije (ISO 23161:2018)
Ta dokument določa metodo plinske kromatografije za ugotavljanje in kvantifikacijo organokositrovih spojin (OTC) v prsteh iz preglednice 1.
Dokument 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.
Organokositrove katione je mogoče določiti samo v skladu s tem dokumentom po derivatizaciji. Anionski del, ki je vezan na organokositrov kation, je odvisen predvsem od kemičnega okolja in se ne določa s to metodo. Peralkilirane organokositrove spojine se obnašajo povsem drugače od njihovih osnovnih spojin. Tetraalkilirane organokositrove spojine, ki so že peralkilirane, kot je tetrabutilkositer, določimo neposredno brez derivatizacije.
Lastnosti, kot so porazdelitev velikosti delcev, vsebnost vode in vsebnost organskih snovi v trdnih snoveh, ki se analizirajo s pomočjo tega dokumenta, se zelo razlikujejo. Priprava vzorca je ustrezno zasnovana in upošteva lastnosti organokositrovih spojin ter matrike za analizo.
