Standard Reference Material (SRM) 1849 Infant/Adult Nutritional Formula has been issued by the National Institute of Standards and Technology (NIST) as a replacement for SRM 1846 Infant Formula, which was issued in 1996. Extraction characteristics of SRM 1846 have changed over time, as have NIST s analytical capabilities. While certified concentration values were provided for 5 constituents in SRM 1846 (4 vitamins plus iodine), 43 constituents are certified in SRM 1849 (fatty acids, elements, and vitamins) and reference concentration values are provided for an additional 43 constituents including amino acids and nucleotides, making it the most extensively characterized food-matrix SRM available from NIST.
