AOAC Method SMPR 2017.011 Instrumentation Guide

Standard Method Performance Requirements (SMPR) for Identification and Quantitation of Free Alpha Amino Acids in Dietary Ingredients and Supplements

AOAC SMPR 2017.011 establishes specific method performance requirements for identifying and quantifying free alpha amino acids in dietary supplements and ingredients. Laboratories must use systems that accurately measure individual amino acids and confirm their identities. To comply with the method, instruments should detect each analyte with an LOQ of ≤ 0.04% and a recommended LOD of ≤ 0.01%. They must also achieve recoveries of 90–107% for levels between 0.04–10% and 98–102% for higher concentrations. Laboratories must maintain RSDr values at or below 5% and RSDR values at or below 8%.
