Water quality - Determination of dalapon, trichloroacetic acid and selected haloacetic acids - Method using gas chromatography (GC-ECD and/or GC-MS detection) after liquid-liquid extraction and derivatization (ISO 23631:2006)

ISO 23631:2006 specifies a method for the determination of dalapon, trichloroacetic acid (TCA) and selected haloacetic acids in ground water and drinking water by gas chromatography (GC-ECD and/or GC-MS detection) after liquid-liquid-extraction and derivatization using diazomethane. Depending on the matrix, the method is applicable to a concentration range from 0,5 to 10 micrograms per litre. The validated reporting limit of TCA and dalapon is about 0,05 micrograms per litre. Detection by electron-capture detector (ECD) in general leads to lower detection limits. Detection by mass spectrometry (MS) allows analyte identification.

Wasserbeschaffenheit - Bestimmung von Dalapon, Trichloressigsäure und ausgewählten Halogenessigsäuren - Verfahren mittels Gaschromatographie (GC-ECD und/oder GC-MS-Detektion) nach Flüssig-Flüssig-Extraktion und Derivatisierung (ISO 23631:2006)

Diese Internationale Norm legt ein Verfahren zur Bestimmung von Dalapon, Trichloressigsäure (TCA) und ausgewählten Halogenessigsäuren (siehe Tabelle 1) mittels Gaschromatographie (GC-ECD und/oder GC-MS-Detektion) in Grund- und Trinkwasser nach Flüssig-Flüssig-Extraktion und Derivatisierung mit Diazomethan fest. In Abhängigkeit von der Matrix kann für das Verfahren von einem Arbeitsbereich zwischen 0,5 µg/l und 10 µg/l ausgegangen werden. Für TCA und Dalapon können niedrigere Konzentrationen bis herab zu 0,05 µg/l bestimmt werden (siehe Tabelle C.1). Die Detektion mittels Elektroneneinfangdetektor (ECD) ermöglicht im Allgemeinen niedrigere Bestimmungsgrenzen; die Detektion mittels Massenspektrometrie (MS) führt zu einer spezifischen Identifizierung.
Die Anwendbarkeit des Verfahrens auf weitere, in Tabelle 1 nicht genannte Verbindungen oder andere Wässer ist nicht ausgeschlossen; sie muss jedoch im Einzelfall geprüft werden.

Qualité de l'eau - Dosage du dalapon, de l'acide trichloroacétique et d'acides haloacétiques selectionnés - Méthode par chromatographie en phase gazeuse (détection CG-DCE et/ou CG-SM) après extraction liquide-liquide et dérivatisation (ISO 23631:2006)

L'ISO 23631:2006 spécifie une méthode de dosage du dalapon, de l'acide trichloroacétique (ATC) et d'acides haloacétiques sélectionnés présents dans les nappes phréatiques et dans l'eau potable par chromatographie en phase gazeuse (détection CG-DCE et/ou CG-SM) après extraction liquide-liquide et dérivatisation à l'aide de diazométhane. En fonction de la matrice, la méthode est applicable dans la plage de concentrations allant de 0,5 microgrammes par litre à 10 microgrammes par litre. Le seuil de quantification validé de l'acide trichloroacétique (ATC) et du dalapon est d'environ 0,05 microgrammes par litre. La détection par un détecteur à capture d'électrons (DCE) conduit généralement à des seuils de détection plus bas. La détection par spectrométrie de masse (SM) permet l'identification d'un analyte.

Kakovost vode - Določevanje 2,2-dikloropropionske kisline (dalapon), trikloroocetne kisline in izbranih halogenoocetnih kislin – Metoda plinske kromatografije z ECD detektorjem in/ali z masno selektivnim detektorjem (GCD-ECD in/ali GC-MS detekcija) po tekočinsko-tekočinski ekstrakciji in derivatizaciji (ISO 23631:2006)
