一般描述

Certified pharmaceutical secondary standards for application in quality control provide pharma laboratories and manufacturers with a convenient and cost-effective alternative to in-house working standards.

应用

α-高生育酚乙酸酯可以用作使用高效色谱(HPLC)测定人血清或血浆样品中α-生育酚的内标。此外,还可用作药物参考标准品,以通过分光光度技术量化药物制剂中的分析物。
这些二级标准品是经过检验的认证标准物质(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

这些二级标准为USP、EP(PhEur)和BP 主要标准提供了多种可追溯性。

其他说明

该认证参考物质(CRM)根据ISO 17034ISO/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。
