List of Reference Materials
A large batch (150 kg wet weight) of tuna (Thunnus thynnus) was collected from the Mediterranean Sea to be used as an intercomparison material. This material was freeze-dried, ground, and sieved through a 250 μm stainless steel sieve. The powder fraction of particle size < 250 μm was further homogenized by mixing in a stainless steel rotating drum for two weeks. Then, aliquots of about 30 g were packaged into glass bottles with aluminum screw caps and sealed with Teflon tape.
