Fertilizers - Determination of N-(1,2-dicarboxyethyl)-D,L-aspartic acid (Iminodisuccinic acid, IDHA) using high-performance liquid chromatography (HPLC)

This European Standard specifies a method for the determination of N-(1,2-dicarboxyethyl)-D,L-aspartic acid (Iminodisuccinic acid (IDHA)) in fertilizers.
The method is applicable to all fertilizers containing IDHA as chelating agent for contents > 0,5 % (g/100 g).

Düngemittel - Bestimmung von N-(1,2-Dicarboxyethyl)-D,L-asparaginsäure (Iminodibernsteinsäure, IDHA) mit Hochleistungs-Flüssigchromatographie (HPLC)

Diese Europäische Norm legt ein Verfahren zur Bestimmung von N-(1,2-Dicarboxyethyl)-D,L-asparaginsäure (Iminodibernsteinsäure, IDHA) in Düngemitteln fest.
Das Verfahren ist auf alle Düngemittel anwendbar, die IDHA als Chelatbildner mit Gehalten von > 0,5 % (g/100 g) enthalten.

Engrais - Dosage de l'acide N-(1,2-dicarboxyéthyl)-D,L aspartique (acide iminodisuccinique, IDHA) par chromatographique liquide haute performance (HPLC)

La présente norme européenne spécifie une méthode de dosage de l’acide N-(1,2-dicarboxyéthyl)-D,L
aspartique (acide iminodisuccinique (IDHA) dans les engrais.
La méthode est applicable à tous les fertilisants contenant de l’IDHA comme agent chélatant dont la teneur
est supérieure à 0,5% (g/100g).

Gnojila - Določevanje N-(1,2-dikarboksietil) D,L asparaginske kisline (iminodijantarna kislina, IDHA) s tekočinsko kromatografijo visoke ločljivosti (HPLC)

Ta evropski standard opredeljuje metodo za določevanje N-(1,2-dikarboksietil) D,L asparaginske kisline (iminodijantarna kislina, IDHA) v gnojilih. Ta metoda se uporablja za vsa gnojila, ki vsebujejo IDHA kot kelatni reagent pri vsebnosti > 0,5 % (g/100 g).
