Determination of the mass fractions of total (As) and inorganic arsenic (iAs) in rice
The IRMM-PT-43 proficiency testing round (PT) focuses on the determination of the mass fractions of total and inorganic arsenic in rice. This PT supports the implementation of Regulation (EU) 2015/1006 amending Regulation (EC) 1881/2006 as regards maximum levels of inorganic arsenic in foodstuffs.
The main objective of this exercise is to assess the analytical capabilities of European official food control laboratories in the determination of total and iAs in rice.
Participation in IRMM-PT-43 is free of charge.
Test materials and analytes
The test material to be analysed is rice. Each participant will receive one jar containing 6 g of the proficiency test item.
The measurands are the mass fractions of total As and iAs in rice.
General outline of the exercise
Participants are requested to perform two or three independent analyses using the method of their choice, and to report the mean of their measurement results, in dry mass and corrected for recovery, its associated expanded measurement uncertainty and the coverage factor k.
Detailed instructions will be sent together with the test item.
