Fertilizers. Determination of chelating agents in fertilizers by chromatography - Determination of [S,S]-EDDS by ion pair chromatography Ingestion-build-103253 Note 4: It is the1 Scope This European Standard 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 distinguishing between the free form and the metal bound form of the chelating agent. This method is applicable to EC fertilizers containing chelates of one
