We are doing science for policy
The Joint Research Centre (JRC) is the European Commission's science and knowledge service which employs scientists to carry out research in order to provide independent scientific advice and support to EU policy.
The EURL-HM-23 proficiency test (PT) focuses on the determination of the mass fraction of total arsenic, cadmium, lead, mercury and inorganic arsenic in palm kernel expeller. This PT is organised in support to DIR 2002/32/EC on undesirable substances in animal feed.
The main objective of this exercise is to assess the analytical capabilities of nominated National Reference Laboratories (NRLs) in the determination of the specific toxic trace elements in palm kernel expeller.
Participation in EURL-HM-23 is open ONLY to NRLs and obligatory for those having mandate for this type of analysis.
Participation is free of charge.
The test material to be analysed is palm kernel expeller. Each participant will receive one test item. The measurands are total As, Cd, Pb, Hg and iAs in palm kernel expeller.
Participants are requested to perform one to three independent analyses using the method of their choice, and to report the mean of their measurement results, the associated expanded measurement uncertainty and coverage factor k.
Detailed instructions will be sent together with the test item.
