Monsters under the bed

Toys can contain the toxin chromium(VI) which is extremely hazardous for children. To protect them, the EU directive 2009/48/EC which came into force in July 2013 and the associated standard EN 71 part 3 set out migration limits and the corresponding test procedures. The ion chromatography described here with inline preconcentration and matrix elimination is suitable for determining chromate in toy materials.
