AOAC Method SMPR 2020.016 Instrumentation Guide

Standard Method Performance Requirements (SMPRs) for Characterization and Quantitation of Component Fractions from Glycerol Esters of Wood Rosin (GEWR)

AOAC SMPR 2020.016 outlines the minimum performance criteria for analytical methods used to quantify and characterize glycerol monoesters, free resin acids, and neutral compounds in Glycerol Esters of Wood Rosin (GEWR). The required limits of quantitation (LOQ) are ≤ 0.01% for both resin acids and neutrals, and ≤ 0.5% for monoesters. Analytical range requirements include 0.01–10% for resin acids, 0.5–10% for monoesters, and 0.01–20% for neutral compounds. Linearity for all analytes must meet or exceed a correlation coefficient (R²) of 0.99.

Method accuracy and precision must also meet strict thresholds. Acceptable recovery is 90–107% for free resin acids and neutrals, and 95–105% for monoesters. Repeatability, expressed as relative standard deviation of repeatability (RSDr), must be ≤ 5.3% for acids and neutrals, and ≤ 3% for monoesters. Reproducibility (RSDR) limits are set at ≤ 8% for acids and neutrals, and ≤ 4.4% for monoesters. These performance criteria ensure that validated methods can reliably separate, quantify, and report on the required GEWR component fractions with high confidence and consistency across different laboratory environments. Suitable platforms include LC-MS/MS systems from Waters, SCIEX, Thermo Scientific, Shimadzu, and PerkinElmer, as well as UV-based HPLC systems like the Agilent 1260 Infinity II.
