AOAC Method SMPR 2015.005 Instrumentation Guide

Standard Method Performance Requirements (SMPR) for Total Vitamin B6 (Pyridoxine) in Infant and Adult/Pediatric Nutritional Formula

AOAC SMPR 2015.005 establishes the method performance criteria for determining total vitamin B6—defined as the sum of pyridoxine, pyridoxal, pyridoxamine, and their 5′-phosphorylated forms—in various nutritional matrices. Applicable matrices include powdered, ready-to-feed, and concentrated forms of infant, adult, and pediatric nutritional formulas. Methods must achieve an LOQ of ≤10 µg/100 g, support an analytical range of 10–2000 µg/100 g, and deliver 90–110% recovery. Additionally, methods must show repeatability (RSDr) of ≤5% and reproducibility (RSDR) of ≤10%, validated using certified reference material such as NIST SRM 1849a.

Detection is typically performed using HPLC with UV, PDA, or fluorescence detection. Chromatographic resolution and sample integrity are critical for accurate quantification across vitamin B6 forms. Instruments must demonstrate sufficient sensitivity, reliable peak integration, and stable performance across diverse product types. The following HPLC systems meet these requirements when configured with validated workflows. Laboratories must internally verify method suitability before use in regulated testing environments.
