General description

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。

Application

乳糖（一水合物）可用作参考标准品，用于通过高效阴离子交换色谱（HPIEC）结合脉冲安培检测来测定食品样品中的乳糖（一水合物）含量。
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标定应用。

Analysis Note

These secondary standards offer multi-traceability to the USP and EP (PhEur) primary standards, where they are available.

Other Notes
