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。乙二醇也可以由化石燃料（石油、天然气和煤）和生物质资源生产得到。它是一种具有广泛工业用途的多元醇。

应用

这些二级标准品是合格的有证标准物质。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。乙二醇可用作使用气相色谱（GC）测定血清样品中存在的乙二醇的标准。

分析说明

这些二级标准品可追溯至 USP、EP（PhEur）和 BP 一级标准品。

其他说明

该认证参考物质（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分析证书上找到。

附注
