Water quality - Determination of selected phenoxyalkanoic herbicides, including bentazones and hydroxybenzonitriles by gas chromatography and mass spectrometry after solid phase extraction and derivatization (ISO 15913:2000)

This International Standard specifies a method for the determination of phenoxyalkanoic acids in ground and
drinking water in mass concentrations W 50 ng/l (detailed information is given in Table A.1 of annex A). Examples
of phenoxyalkanoic acids which can be determined by this method are given in Table 1.
This method may be applicable to compounds not mentioned in Table 1 or to other types of water. However, it is
necessary to verify the applicability of this method for these special cases (see annex B).
Table 1 — Plant treatment agents determined by this method

Wasserbeschaffenheit - Bestimmung ausgewählten Phenoxyalkancarbonsäure-Herbiziden, einschließlich Bentazon und Hydroxybenzonitrilen mittels Gaschromatographie und massenspektrometrischer Detektion nach Fest-Flüssig-Extraktion und Derivatisierung (ISO 15913:2000)

Diese Internationale Norm legt ein Verfahren zur Bestimmung von Phenoxyalkancarbonsäuren in Grund- und Trinkwasser in Massenkonzentrationen = 50 ng/l fest (genauere Information siehe Tabelle A.1 in Anhang A). Beispiele für Phenoxyalkancarbonsäuren, die nach diesem Verfahren bestimmt werden können, siehe Tabelle 1.
Die Anwendbarkeit des Verfahrens auf weitere, in Tabelle 1 nicht genannte Verbindungen ist nicht ausgeschlossen; sie muss jedoch im Einzelfall geprüft werden (siehe Anhang B).

Qualité de l'eau - Dosage de certains herbicides phénoxyalcanoïques, y compris bentazones et hydroxybenzonitriles, par chromatographie en phase gazeuse et spectrométrie de masse après extraction en phase solide et dérivatisation (ISO 15913:2000)

La présente Norme internationale spécifie une méthode de dosage des herbicides phenoxyalcanoïques présents
dans les eaux souterraines et les eaux destinées à la consommation humaine en concentrations en masse
W 50 ng/l (des informations détaillées sont données dans le Tableau A.1 de l'annexe A). Des exemples d'acides
phénoxyalcanoïques pouvant être déterminés par la présente méthode sont donnés dans le Tableau 1.
La présente méthode peut être appliquée à d'autres composés ne figurant pas dans le Tableau 1 ou à d'autres
types d'eau. Il convient toutefois de contrôler l'applicabilité de la présente méthode à ces cas spéciaux (voir
l'annexe B).
