Description
|
Organics in Mussel Tissue (Mytilus edulis) Standard Reference Material (SRM) 1974b is a frozen mussel tissue homogenate intended for use in evaluating analytical methods for the determination of selected polycyclic aromatic hydrocarbons (PAHs), polychlorinated biphenyl (PCB) congeners, and chlorinated pesticides in marine bivalve mollusk tissue and similar matrices. All of the constituents for which certified and reference values are provided in SRM 1974b were naturally present in the tissue material before processing. keywords: biological materials , animal tissue , foodstuff , trace elements , heavy metals , mercury speciation , speciation analysis , organometallics , Fish/Shellfish |
Package |
A unit of SRM 1974b consists of five bottles each containing approximately 8 g to 10 g (wet basis) of frozen tissue homogenate. |
