Fertilizers - Determination of urea condensates using high-performance liquid chromatography (HPLC) - Isobutylidenediurea and crotonylidenediurea (method A) and methylene-urea oligomers (method B)
This European Standard specifies methods for the determination of isobutylidenediurea (IBDU), crotonylidenediurea (CDU) (method A) and methylene-urea oligomers (MU) (method B) in fertilizers using high-performance liquid chromatography (HPLC). The method is applicable to all fertilizers which do not contain interfering organic compounds.
Düngemittel - Bestimmung von Harnstoffkondensaten mit Hochleistungs-Flüssigchromatographie (HPLC) - Isobutylidendiharnstoff und Crotonylidendiharnstoff (Verfahren A) und Methylenharnstoff-Oligomere (Verfahren B)
Diese Europäische Norm legt Verfahren für die Bestimmung von Isobutylidendiharnstoff (IBDU), Crotony-lidendiharnstoff (CDU) (Verfahren A) und Methylenharnstoff-Oligomere (MU) (Verfahren B) in Düngemitteln mit Hochleistungs-Flüssigchromatographie (HPLC) fest.
Das Verfahren gilt für alle Düngemittel, die keine störenden organischen Verbindungen enthalten.
Engrais - Dosage des condensats d'urée par chromatographie liquide haute performance (HPLC) - Isobutylidène diurée et crotonylidène diurée (méthode A) et oligomères de méthylene-urée (méthode B)
La présente Norme européenne spécifie les méthodes de dosage de l’isobutylidène diurée (IBDU), de la crotonylidène diurée (CDU) (méthode A) et des oligomères de méthylène-urée (MU) (méthode B) dans les engrais par chromatographie liquide haute performance (HPLC).
La méthode est applicable à tous les engrais qui ne contiennent pas de composés organiques interférents.
