SRM 1946 Lake Superior Fish Tissue

SRM 1946 Lake Superior Fish Tissue - This Standard Reference Material (SRM) is a frozen fish tissue homogenate that was prepared from lake trout (Salvelinus namaycush namaycush) collected near the Apostle Islands in Lake Superior (U.S./Canada), and is intended primarily for use in evaluating analytical methods for the determination of polychlorinated biphenyl (PCB) congeners, chlorinated pesticides, polybrominated diphenyl ether (PBDE) congeners, perfluorooctanesulfonic acid (PFOS), fatty acids (including omega-3 fatty acids), extractable fat, methylmercury, total mercury, proximates , ?-hexabromocyclododecane (?-HBCD), and selected trace elements in fish tissue and similar matrices. All of the constituents for which certified, reference, and information mass fraction values are provided are naturally present in the fish tissue homogenate. A unit of SRM 1946 consists of five bottles, each containing approximately 7 g to 9 g (wet basis) of frozen tissue homogenate. This data is public in the Certificate of Analysis for this material.

SRM 1946 苏必利尔湖鱼类组织——本标准参考物质（Standard Reference Material, SRM）为冷冻鱼组织匀浆，由采自美加边境苏必利尔湖使徒群岛附近的湖鳟（*Salvelinus namaycush namaycush*）制备而成。其主要用途为评估鱼类组织及类似基质中多氯联苯（Polychlorinated Biphenyl, PCB）同系物、氯化农药、多溴二苯醚（Polybrominated Diphenyl Ether, PBDE）同系物、全氟辛烷磺酸（Perfluorooctanesulfonic Acid, PFOS）、脂肪酸（包括Omega-3脂肪酸）、可提取脂肪、甲基汞、总汞、近似组分、α-六溴环十二烷（α-hexabromocyclododecane, α-HBCD）以及选定痕量元素的分析检测方法。本物质所提供的定值、参考及信息质量分数对应的所有组分，均天然存在于该鱼组织匀浆中。每份SRM 1946包含5支容器瓶，每瓶含约7 g至9 g（湿基）冷冻组织匀浆。本项数据公开于该物质的分析证书（Certificate of Analysis）中。
