一般描述
用于质量控制的制药二级标准品，为制药实验室和制造商制备内部工作标准品提供了一种方便、高性价比的替代方案。
应用
胞嘧啶可作为药物标准品，通过毛细管区带电泳和色谱技术测定药物制剂中的分析物。
这些二级标准品是合格的认证标准物质（CRM）。它们适用于多种分析应用，包括但不限于药物释放测试、药物的定性和定量分析方法开发、食品和饮料质量控制检测以及其他校准需求。
分析说明
These secondary standards offer multi-traceability to the US and EP primary standards, where they are available.
其他说明
想要查看本品的检验报告示例，请在下框中输入LRAA1102。这只是一个示例证书，可能与您收到的批次不符。
该认证标准物质（CRM）根据ISO 17034 和 ISO/IEC 17025进行生产和认证。有关此CRM使用的所有信息均可在检验报告上找到。
