AOAC Method SMPR 2015.002 Instrumentation Guide

Standard Method Performance Requirements (SMPR) for Total Vitamin B1 (Thiamin) in Infant and Adult/Pediatric Nutritional Formula

AOAC SMPR 2015.002 outlines minimum performance criteria for quantifying total vitamin B1, or thiamin, in fortified nutritional formulas. The method applies to powdered, liquid, and concentrated infant, adult, and pediatric nutrition products. Total vitamin B1 includes thiamin and its phosphorylated forms, and results must be expressed as thiamin. Laboratories must ensure methods support an analytical range of 20–2000 µg/100 g, with an LOQ of ≤20 µg/100 g. Recovery must fall between 90–110%, with repeatability (RSDr) ≤5% and reproducibility (RSDR) ≤10%.

Instruments should provide low detection limits, stable baselines, and accurate retention times across complex matrices. Analysts typically use high-performance liquid chromatography (HPLC) with UV, DAD, or FLR detection to meet these demands. Reference materials such as NIST SRM 1849a help confirm method accuracy. The instruments listed below meet AOAC performance standards when paired with validated methods. These platforms support reliable results in both regulatory and high-throughput environments.
