Description
|
Sixty kg of clams (Gafrarium tumidum) were collected in Noumea, New Caledonia. Clams were opened, the soft-shell part was frozen and then freeze dried. The dry material was first ground and sieved at 250 μm. A portion of about 5 kg was micronized to achieve a final powder size <50 μm. The homogenization was performed by mixing the material in a stainless steel rotating homogenizer
Moritz ERM-BB124 (Moritz, Chatou, France) for 14 days at a temperature of 20 (±2)°C and relative humidity of 50%. After checking for the homogeneity of sample material, aliquots of about 8 g were packed into pre-cleaned brown borosilicate glass bottles with polyethylene caps and then sealed in plastic bags. The sample material was labelled as IAEA-461. keywords: biological material , animal tissue , foodstuff , fish/shellfish , trace elements , speciation analysis , mercury speciation
