DD CEN/TS 15705:2009 Fertilizers. Determination of urea condensates using high-performance liquid chromotography (HPLC). Isobutylidenediurea and crotonylidenediurea (method A) and methylen-urea oligomers (method B)

DD CEN/TS 15705 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 specified in DD CEN/TS 15705 is applicable for all fertilizers which do not contain interfering organic compounds.
