Total As, Cd, Pb and Hg in compound feed
The IMEP-117 proficiency testing (PT) exercise focuses on the analysis of total arsenic, cadmium, lead and mercury in compound feed. This PT is organised in support to Directive 2002/32/EC of the European Parliament and of the Council on undesirable substances in animal feed, which sets maximum levels for certain contaminants in feed and contributes to the implementation of high quality and uniform analytical results.
The main objective of this exercise is to assess the capabilities of nominated National Reference Laboratories (NRLs) in the determination of heavy metals in compound feed, which maximum limits are set according to Directive 2002/32/EC.
Participation in IMEP-117 is mandatory for all NRLs having experience in this kind of analysis. Only appointed NRLs can participate in this exercise.
Registration is free of charge.
Test materials and analytes
The test material to be analysed is compound feed contained in a glass bottle. Each participant will receive one bottle of the test item.
The measurands are total As, Cd, Pb and Hg in compound feed.
General outline of the exercise
Participants are requested to perform 1 - 3 independent analyses using the method of their choice, and to report their result for the PT assessment, its associated measurement uncertainty and coverage factor k.
Detailed instructions will be sent together with the test sample.
