Fertilizers - Determination of 1H-1,2,4-triazole in urea and in fertilizers containing urea - Method using high-performance liquid chromatography (HPLC)

This European Standard specifies a method for the determination of triazole (TZ) in urea or in fertilizers containing urea in the presence of dicyandiamide or methylpyrazole respectively using high-performance liquid chromatography (HPLC).

Düngemittel - Bestimmung von 1H-1,2,4-Triazol in Harnstoff und harnstoffhaltigen Düngemitteln - Verfahren mit Hochleistungs-Flüssigchromatographie (HPLC)

Diese Europäische Norm legt ein Verfahren zur Bestimmung von Triazol (TZ) in Harnstoff oder in harnstoffhaltigen Düngemitteln jeweils in Anwesenheit von Dicyandiamid oder Methylpyrazol mittels Hochleistungs-Flüssigchromatographie (HPLC) fest.

Engrais - Dosage du 1H-1,2,4-triazole dans l'urée et les engrais contenant de l'urée - Méthode par chromatographie liquide à haute performance (HPLC)

La présente norme décrit une méthode de détermination de la teneur en triazole (TZ) dans l’urée et dans les
engrais contenant de l’urée en présence de dicyandiamide ou de méthylpyrazole par chromatographie liquide
à haute performance (HPLC).

Gnojila - Določevanje 1H,2,4-triazola v sečnini in gnojilih, ki vsebujejo sečnino - Metoda s tekočinsko kromatografijo visoke ločljivosti (HPLC)

Ta dokument določa metodo za določevanje triazola (TZ) v sečnini ali gnojilih, ki vsebujejo sečnino, v prisotnosti diciandiamida oz. metilpirazola, z uporabo plinske kromatografije (GC). Triazol se določa s plinsko kromatografijo. Zaznava poteka prek kvadrupola. Pri analizi se uporablja zunanja kalibracijska točka. Pri kalibraciji je treba ustrezno upoštevati sečnino ali raztopino amonijevega nitrata in sečnine ter druge zaviralce nitrifikacije, npr. diciandiamid oz. metilpirazol, ki sta prisotna v njih (matrični interferenčni učinek).
