AOAC Method SMPR 2020.015 Instrumentation Guide

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

AOAC SMPR 2020.015 defines the analytical performance requirements for methods used to quantify monoesters in Glycerol Esters of Wood Rosin (GEWR). These monoesters are derived from abietic-type acids, pimaric-type acids, and dehydroabietic acid. The method must measure both individual and total monoester concentrations in complex GEWR mixtures. Analytical systems must meet a limit of quantitation (LOQ) of ≤ 0.5% and demonstrate linearity within an analytical range of 0.5% to 10%. Methods must also achieve a recovery between 95% and 105%, with repeatability (RSDr) ≤ 3% and reproducibility (RSDR) ≤ 4.4%.

The method must also distinguish monoesters from related GEWR components such as diesters, free acids, and neutral substances. Acceptable instrumentation includes LC-MS/MS for high-sensitivity workflows, GC-MS with derivatization for volatile components, or HPLC with UV or ELSD detection for UV-active monoesters. The instruments listed below meet these rigorous criteria and are well-suited for regulated laboratory environments and product validation workflows.
