美国药典（USP）标准品
美国药典（USP）标准物质
USP法定标准物质是原料药、辅料、杂质、降解产品、食品补充剂、药典试剂和性能校正剂的样品，其特性规定极严密。在进行法定 USP-NF 测试和化验时必须使USP 标准物质。
标准物质通常用于进行 USP-NF 的下列测试：
➣ 鉴定测试
➣ 杂质或相关化合物的有限测试
➣ 原料药和配方的化验
➣ 系统适用性测试
USP 标准物质也可以用作校正剂，用于溶出、粒子计数、熔点和滴定液标定，也可以用于空白和对照实验。标准物质主要用于色谱和光谱程序。
除基于 USP-NF 的标准物质之外，USP还向分析、临床、制药和研究实验室提供《食品化学法典》(Food Chemicals Codex)中规定的标准物质以及纯品(优质化学样品)。以及残留溶剂标准品。如：
