This document specifies the method for the determination of free, chelated or complexed micronutrients and chelating and\/or complexing agents present in compound inorganic micronutrient fertilizers. This method applies to compound inorganic micronutrient fertilizers when micronutrients are chelated and\/or complexed. The method is based on the determination of the following specific parameters : – the water-soluble micronutrient concentration; – the fraction of chelated micronutrients in relation; – identification of chelating agents EDTA, DTPA, HEEDTA, IDHA, [S,S]\u2013EDDS, [o,o] EDDHA, [o,o] EDDHMA, [o,p] EDDHA, HBED and EDDHSA; – the fraction of complexed micronutrients; – identification of complexing agents (lignosulfonates, heptagluconic acid (HGA)). The method is based on – ICP (inductive coupled plasma) or FAAS (flame atomic absorption spectrometry) measurement of the concentration of water-soluble micronutrients according to EN 16963 or EN 16965 after extraction according to EN 16962; – LC (liquid chromatography) measurement of the chelating agents according to EN 15950, EN 13368-1, EN 13368-2, EN 13368-3, EN 15451, EN 15452; and\/or complexing agents according to EN 16109 and EN 16847; – determination of the concentration of chelated micronutrients by CEN\/TS 17786-1 and\/or CEN\/TS 17786-2; – determination of the complexed micronutrients by EN 15962. To avoid duplication of the analytical methods, CEN\/TS 17786-2 describes the determination of micronutrients and the identification and determination of chelating agents.<\/p>\n
