Additional information

The water solubility of the zinc complex dye of the test item Zinc-Azo barbituric acid / Melamine in demineralized water was determined by the zinc content of the aqueous phases determined by ICP-MS, calculated with the zinc content of the zinc complex dye Zinc-Azo barbituric acid / Melamine (purity 100 %) determined by ICP-OES.
