Analysis of total Cd, Pb, As, Hg and Sn and extractable amounts of Cd and Pb in feed of plant origin

IMEP-29 Total As, Cd, Pb, Hg, Sn and extractable Cd and Pb in feed of plant origin

The IMEP-29 exercise focused on the analysis of total As, Cd, Pb, Hg, Sn and extractable Cd and Pb. This interlaboratory comparison ran in parallel to IMEP-108 where only appointed National Reference Laboratories could take part in.

This exercise was open to all laboratories, but only the first 60 registrations could be admitted.

The cost of this interlaboratory comparison was EUR 210 per registration.

Test materials and analytes

The test material to be analysed was feed of plant origin contained in a brown glass bottle. Each participant received one bottle. The measurands were total As, Cd, Pb, Hg, Sn and extractable Cd and Pb.

General outline of the exercise

Participants were requested to perform 1-3 independent analyses using the method of their choice.
