Analysis of total Cd, Pb, As and Hg in food supplements

IMEP-28 total Cd, Pb, As and Hg in food supplements

The IMEP-28 focussed on the analysis of total Cd, Pb, As and Hg in food supplements. This interlaboratory comparison ran in parallel to IMEP-106 where only appointed National Reference Laboratories could take part in.

This exercise was open to all laboratories.
