Determination of total As, Cd, Cu, Pb and Hg, as well as the extractable amounts of Cd and Pb in mineral feed

The IMEP-31 exercise focused on the analysis of total arsenic, cadmium, copper, lead, and mercury as well as the extractable amounts of cadmium and lead. This interlaboratory comparison ran in parallel to IMEP-111 where only appointed National Reference Laboratories could take part in.

IMEP-31 exercise was open to all laboratories.

The cost of this interlaboratory comparison was EUR 250 per registration.

Test material and analytes

The test material to be analysed was mineral feed contained in a glass bottle. Each participant received one bottle. The measurands were total As, Cd, Cu, Pb, and Hg, as well as extractable Cd and Pb.

General outline of the exercise

Participants were requested to perform 1 - 3 independent analyses using the method of their choice, and to report the mean, its expanded uncertainty and coverage factor. Detailed instructions have been sent together with the sample.
