简介:
NIST的科学家主要从事生物技术、化学、半导体电子学、陶瓷学、物理学、光电子学、防火、聚合物、信息技术、制造工程和计量科学。NIST每年的运行经费大约为86400万美元。目前拥有4600位研究人员和流动人员,其中科研、技术、后勤和管理人员有3000人,其中有两位诺贝尔奖获得者。另外有1600余名客座研究人员。此外,NIST在全国的附属中心还有2000名制造业专家和工作人员。
NISTStandardReferenceMaterials(简称SRMs)是美国国家标准局(NIST)制定的“标准参照样品(SRM)”,共有1100多种,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,SRM标准参照样品的适用范围:(1)帮助开发准确的分析方法,(2)用于校正检测仪器、质量控制和测定检出极限,(3)保证检测方法的可靠性和长久稳定性。
