A large batch of mussels (Mytilus edulis) was collected from the North Sea to be used as an intercomparison material. This material was freeze-dried and ground. It was further sieved through a 250 μm stainless steel sieve. The mussel powder fraction of particle size less than 250 μm was further homogenized by mixing in a rotating drum for two weeks. Then, aliquots of about 45 grams were packaged into glass bottles with aluminum screw caps and sealed with Teflon tape.
