ASP-Mus-d Mussel Tissue Certified Reference Material for Domoic Acid
Domoic Acid (DA) is a toxin responsible for incidents of amnesic shellfish poisoning (ASP) on the east and west coasts of North America [1,2]. CRM-ASP-Mus-d is a mussel tissue (Mytilus edulis) homogenate containing DA, as well as several related compounds (Figures 1 and 2). This is a replacement CRM for the depleted product CRM-ASP-Mus-c which was released in 2005. The tissue was thermally stabilized, homogenized, heat sealed in polypropylene bottles and packed in trilaminate pouches. Each pouch contains two 4 g bottles of homogenate with DA at levels appropriate for analytical testing. The concentration of DA and the epimeric C5’-epi-DA in CRM-ASP-Mus-d was assigned using a high recovery extraction method and quantitation by liquid chromatography with both UV absorbance and mass spectrometric detection (Table 1)./贻贝组织软骨藻酸标准物质
软骨藻酸（DA）是一种毒素，可导致北美东海岸和西海岸的健忘性贝类中毒事件[1,2]。CRM-ASP-Mus-d是一种贻贝组织（贻贝）匀浆，含有DA以及几种相关化合物（图1和图2）。这是2005年发布的耗尽产品CRM-ASP-Mus-c的替代CRM。组织经过热稳定、均质化、热封在聚丙烯瓶中，并包装在三层袋中。每个袋子里装有两瓶4克的匀浆，其中DA的含量适合分析测试。使用高回收率提取法和液相色谱定量法，结合紫外吸收和质谱检测，确定CRM-ASP-Mus-d中DA和差向异构C5′-epi-DA的浓度（表1）。软骨藻酸贻贝组织CRM-ASP-Mus
