BS EN 15705-2010 肥料.利用高效液相色谱法(HPLC)进行尿素固化物测定.异丁叉双尿素和丁烯叉二脲(方法A)以及次甲基尿素低聚物(方法B)
Fertilizers - Determination of urea condensates using high-performance liquid chromatography (HPLC) - Isobutylidenediurea and crotonylidenediurea (method A) and methylen-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.
