Description
|
Frozen dogfish liver was sourced and prepared by Guelph Food Technology Center (Guelph, ON, Canada) where the liver was comminuted (50 μm), blended, partially defatted at 40 oC, and freeze-dried. The dried dogfish liver meal was then defatted by POS Bio-Sciences (Saskatoon, SK, Canada) using hexane to produce free-flowing powder. The defatted samples were bottled at NRC and radiation sterilized with a minimum dose of 25 kGy by Nordion Gamma Centre of Excellence (Laval, QC, Canada) to minimize any effects from biological activity.
This reference material is primarily intended for use in the calibration of procedures and the development of methods for the determination of trace and matrix constituents in marine fauna and materials with similar matrices. A minimum sample mass of 250 mg is recommended. keywords: Biological material, Animal tissue, Foodstuff, Fish/Shellfish, Trace elements, Heavy metals, Speciation analysis, Arsenic speciation |
