Chromate (Cr(VI)) is considered toxic and potentially carcinogenic, which is why its concentrations in children's toys should be kept as low as possible. The EU directive 2009/48/EC defines limit values for the migration of chromate from children's toys. The hydrochloric-acid-containing migration solution is diluted with a buffer. 2000 μL of this solution are injected automatically using intelligent preconcentration technology and matrix elimination. Detection takes place via ICP/MS.
