USP標準品USP殘留溶劑-北京綠百草提供
USP標準物質在130多個國家得到廣泛的認可和信任。USP 法定標準物質是原料藥、輔料、雜質、降解產(chǎn)品、食品補充劑、藥典試劑和性能校正劑的樣本，其特性規(guī)定極嚴密。在進行法定 USP-NF 測試和化驗時必須使用USP 標準物質。
USP標準物質也可以用作校正劑，用于溶出、粒子計數(shù)、熔點和滴定液標定，也可以用于空白和對照實驗。標準物質主要用于色譜和光譜方法。除基于USP-NF的標準物質之外，USP 還向分析、臨床、制藥和研究實驗室提供《食品化學法典》（Food Chemicals Codex）中規(guī)定的標準物質以及純品（優(yōu)質化學樣品）。
