Fertilizers - Determination of complexing agents in fertilizers - Identification of heptagluconic acid by chromatography

This European Standard specifies a chromatographic method which allows the identification of heptagluconic acid (HGA) in fertilizers containing heptagluconic acid metal complexes.
This method is applicable to EC fertilizers containing complexed micro-nutrients, which are covered by Regulation (EC) No 2003/2003 [1].

Düngemittel - Bestimmung von Komplexbildnern in Düngemitteln - Identifikation von Heptaglukonsäure mit Chromatographie

Diese Europäische Norm legt ein chromatographisches Verfahren zur Identifizierung von Heptaglukonsäure (HGA) in Düngemitteln fest, die Heptaglukonsäure-Metallkomplexe enthalten.
Dieses Verfahren gilt für Düngemittel mit komplexgebundenen Spurennährstoffen die den Anforderungen der Verordnung (EG) Nr. 2003/2003 [1] unterliegen.

Engrais - Détermination des agents complexants dans les engrais - Identification de l'acide heptagluconique par chromatographie

La présente norme européenne spécifie une méthode d'identification par chromatographie de l'acide heptagluconique (HGA) dans les engrais contenant des complexes métalliques de l’acide heptagluconique.
Cette méthode s'applique aux engrais CE contenant des oligoéléments complexés qui sont couverts par le Règlement (CE) n° 2003/2003 [1].

Gnojila - Določevanje kompleksirajočih agensov v gnojilih - Prepoznavanje heptaglukonske kisline s kromatografijo

Ta evropski standard določa kromatografsko metodo, ki omogoča prepoznavanje heptaglukonske kisline (HGA) v gnojilih, ki vsebujejo kovinske komplekse heptaglukonske kisline.
Ta metoda se uporablja za gnojila ES, ki vsebujejo kompleksna mikrohranila, obravnavana v Uredbi (ES) št. 2003/2003 [1].
