This Standard Reference Material (SRM) is intended primarily for validation of methods for determining proximates, fatty acids, cholesterol, vitamins, elements, amino acids, and nucleotides in infant and adult nutritional formulas and similar materials. This SRM can also be used for quality assurance when assigning values to in-house reference materials. The SRM is a milk-based, hybrid infant/adult nutritional powder prepared by a manufacturer of infant formula and adult nutritional products. A unit of SRM 1849a consists of 10 packets, each containing approximately 10 g of material.

Infant/Adult Nutritional Formula (NIST-1849a) :
产品详细 :Each packet contains approximately 10 grams of a milk-based powder, a blend of material similar to the infant and adult versions of just-add-water nutritional powders you can buy in the grocery store. The material, provided by a manufacturer, is close to the consumer versions, but is "not an actual infant formula, because you don't want it to be confused with anything real," says Melissa Phillips, one of the NIST scientists who coordinated the analysis of this reference material. It's not so important that the material matches an actual consumer product, just that it's been assessed with NIST's usual rigor and is available for others to do the same. Other Notes

美国国家标准技术研究所(National Institute of Standards and Technology,简写为NIST)的前身为国家标准局(NBS,1901年~1988年),是一家测量标准实验室,属于美国商务部的非监管机构。该研究所的官方使命为:
Promote U.S. innovation and industrial competitiveness by advancing measurement science, standards, and technology in ways that enhance economic security and improve our quality of life.
促进美国的创新和产业竞争力,推进度量衡?W、标准、技术以提高经济安全并改善我们的生活质量。
NIST雇佣有大约2900名科学家、工程师、科技工作者,以及后勤和管理人员,大约1800名辅助工作人员(来自美国公司和国外的工程师和研究员),另外还有1400名专家分布在国内约350个附属研究中心里。
NIST总部位于马里兰州的盖瑟斯堡,在科罗拉多州的博尔德市亦有设施运作。主要活动为组织实验室研究计划和校外研究计划。自2010年10月1日起,NIST将所属的10间实验室进行了调整,减为6间。
