The EU-RL for Dioxins and PCBs in Feed and Food organizes a proficiency test (PT) on the determination of PCDD/Fs, dioxin-like PCBs and Indicator PCBs in pork and lard to be performed between February and April 2012.
The objective is to assess analytical performance of laboratories and the interlaboratory comparability of results from all relevant parameters.

In addition, this specific PT is focusing on

• the assessment of the analytical performance of alternative physico-chemical techniques to GC/HRMS methods (e.g.GC-MS/MS) for determination of PCDD/Fs and dioxin-like PCBs. Laboratories applying these methods for PCDD/F and DL-PCB analysis are especially encouraged to participate in this PT.
  
  
• the application of the measurement uncertainty.

This PT is open for

• National Reference Laboratories (NRLs) of EU member states
• National Reference Laboratories of other European countries
• Official Laboratories (OFLs) of EU member states and other European countries
• Other official and commercial laboratories (PCDD/Fs and DL-PCBs only)

The participation of NRLs of EU member states is free of charge, other participants will be charged a fee for participation.

Further information on this PT can be found in the announcement of this PT:
Announcement - EU-RL PT PCDD/Fs and PCBs in Pork and Lard 2012

The deadline for reporting of the results and method information is 20th April 2012.
