Chromate in Toy Migration Solution
8 Jan 2015Chromate (Cr(VI)) is considered toxic and potentially carcinogenic for which reason its concentrations should be as low as possible. EU directive 2009/48/EC defines limits for chromate migrating from toys. In this application note, a sample plastic toy is injected with hydrochloric acid migration solution. This solution is then injected by Metrohm intelligent Preconcentration Technique and Inline Matrix Elimination (MiPCT-ME). Chromate detection is performed by UV-VIS-Detection after post-column reaction with diphenylcarbazide.
