Fertilizers - Determination of urea condensates using high-performance liquid chromatography (HPLC) - Isobutylidenediurea and crotonylidenediurea (method A) and methylen-urea oligomers (method B)

Fertilizers containing the condensates of urea and specified aldehydes (with crotonaldehyde called crotonyliden diurea or CDU, with isobutyraldehyde called isobutylidene diurea or IBDU, with formaldehyde called urea formaldehyde or methylene urea or MU) are covered by Annex I of the Regulation (EC) 2003/2003 [1] as nitrogenous fertilizers. The methods described in this European Standard enable the quantitative determination of these condensates and the determination of the solubility of the MU-oligomers according to the Regulation.

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 méthylène-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.

Gnojila - Določevanje kondenzatov sečnine s tekočinsko kromatografijo visoke ločljivosti (HPLC) - Izobutilidendiurea in krotonilidendiurea (metoda A) in oligomeri metilenuree (metoda B)

Ta evropski standard določa metode za določevanje izobutilidendiura(IBDU), krotonilidendiurea(CDU) (metoda A) ter oligomeri metilenuree (MU) (metoda B) v gnojilih s tekočinsko kromatografijo visoke ločljivosti (HPLC). Metoda se uporablja za vsa gnojila, ki ne vsebujejo motečih organskih spojin.
