Fertilizers - Determination of chelating agents in fertilizers by chromatography - Part 2: Determination of Fe chelated by o,o-EDDHA, o,o-EDDHMA and HBED by ion pair chromatography; German version EN 13368-2:2012
Preview
Summary
The European Standard specifies a method for the chromatographic determination of the iron chelated by each individual ortho(hydroxy)-ortho(hydroxyl) isomer of the chelating agents o,o-EDDHA, o,o-EDDHMA and by HBED in fertilizers containing one or more of these substances. The method allows the identification and the determination of the total concentration of water soluble iron chelates of these chelating agents. The method is not applicable for the determination of the free form of the chelating agents.This procedure concerns EC fertilizers covered by Regulation (EC) No 2003/2003. It is applicable to a mass fraction of the metal chelated of at least 0,625 %.
