Application
叶酸可作为药物参考标准品,用于通过紫外分光光度技术和微乳电动毛细管色谱对药物制剂中的分析物进行定量。
这些二级标准品是经认证过的有证标准物质(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。
General description
叶酸主要来源于膳食本身,也可从维生素药片等药品中获取。†服用叶酸对于预防神经管缺陷(主要为无脑畸形和脊柱裂)十分必要。†它属于水溶性维生素B族成员。主要用于强化杂粮/谷物和膳食补充剂。
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。
Other Notes
要查看该材料的分析证书示例,请在下面的栏位中输入LRAB7352。这只是一个示例证书,可能不是您收到的批次。
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。
Analysis Note
These secondary standards offer multi-traceability to the USP and EP (PhEur) primary standards, where they are available.
