IMEP-114

Total Cd, Pb, As, Hg and Sn in Feed pre-mixes

The IMEP-114 exercise focuses on the analysis of total cadmium, lead, arsenic, mercury and tin in feed pre-mixes. This interlaboratory comparison (ILC) is organised in the frame of Directive 2002/32/EC, and contributing to the implementation of high quality and uniform analytical results, on the determination of heavy metals in feed pre-mixes.
The main objective of this exercise is to evaluate the capabilities of nominated national reference laboratoties in the determination of heavy metals according to Directive 2002/32/EC. Participation in IMEP-114 is mandatory for all NRLs having experience in this kind of analysis.

Only appointed National Reference Laboratories can participate in this exercise.

Registration is free of charge.

Test materials and analytes

The test material to be analysed is feed pre-mix contained in a glass bottle. Each participant will receive one bottle. The measurands are total Cd, Pb, As, Hg and Sn in feed pre-mix.

General outline of the exercise

Participants are requested to perform 1-3 independent analysis using the method of their choice, and to report the mean, its expanded uncertainty, and the coverage factor k. Detailed instructions will be send together with the sample.
