Arsenic species in rice: Call for analytical laboratories
(04.01.2011)
The Institute for Reference Materials and Measurements (IRMM) is looking for analytical laboratories which can quantify arsenic species in rice.
The European Commission's JRC-IRMM is planning a certification campaign for total arsenic and arsenic species in rice. For this reason IRMM is looking for labs which can quantify total arsenic, arsenite/arsenate (sum) and dimethylarsinic acid (DMA) in rice using techniques other than ICP-MS or LC/ICP-MS for arsenic speciation analysis. The concentration ranges are as followed: - Total arsenic (50-500 ng/g)
- Arsenite and arsenate (sum; 50-300 ng/g)
- DMA (50-300 ng/g)
In order to ensure high quality data validated methods, a quality system and/or accreditation to ISO/IEC 17025 is mandatory.
