Resumen:
The document specifies a method for the chromatographic determination of the chelating agent [S,S]-EDDS in fertilizers. The method allows the identification and the determination of the total concentration of the water soluble fraction of this chelating agent. It does not allow to distinguish between the free form and the metal bound form of the chelating agent. This method is applicable to EC-fertilizers containing chelates of one or more of the following micro-nutrients: cobalt, copper, iron, manganese and zinc covered by Regulation (EC) No 2003/2003. It is applicable to a mass fraction of the metal chelated of at least 0,35 %.
