美国NIST标准品SRM目录、价格表
摘要：美国国家标准技术研究所，National Institute of Standards and Technology (NIST)，前身为国家标准局（NBS，1901年~1988年），是一家测量标准实验室，属于美国商业部的技术管理部门，前身是1901年建立的联邦政府的第一个物理科学实验室，位于马里兰州的Gaithersburg，是目前NIST总部所在地，占地234公顷，另一分部，位于科罗拉多州的Boulder,占地84公顷，还有两个设在大学的联合研究所，JILA在Colorado大学，CARB在Maryland大学。NIST主要从事物理、生物和工程方面的基础和应用研究，以及测量技术和测试方法方面的研究，提供标准、标准参考数据及有关服务，在国际上享有很高的声誉。
NIST Standard Reference Materials 简称(SRMs)是美国国家标准局(NIST) 制定的“标准参照样品 (SRM)”。NIST为产业界、学术界、政府及其他用户提供了超过1100种标准参考材料。每种标样都有美国国家标准局的详细分析报告和用途说明，这些物品经认证后被作为特定的量度或成分含量，成为校正标准用于测量设备和制作程序、工业生产的品质控制标准，以及实验对比样本。
