AOAC Method SMPR 2021.008 Instrumentation Guide

Standard Method Performance Requirements (SMPRs) for Glyphosate, its Metabolites, and Trimesium in Fruits and Vegetables, Cereals, Food of Animal Origin, Pet Food, and Baby Food

AOAC SMPR 2021.008 outlines the minimum analytical performance requirements for quantifying glyphosate, AMPA, N-acetyl-glyphosate, N-acetyl-AMPA, and Trimesium in food. The method supports liquid chromatography-tandem mass spectrometry (LC-MS/MS) as the preferred platform due to its high specificity and suitability for polar analytes. To meet compliance, laboratories must achieve a limit of quantitation (LOQ) of ≤ 0.01 mg/kg (10 µg/kg) for baby food and ≤ 0.05 mg/kg (50 µg/kg) for all other matrices. Each analyte must also be recoverable at 70–120% across relevant food categories.

Precision requirements include a repeatability (RSD_r) of ≤ 20% and a reproducibility (RSD_R) of ≤ 25%, ensuring consistent performance across both routine and multi-lab environments. Methods must also demonstrate no significant matrix interference at the method LOQ for each target analyte. Because glyphosate and its metabolites are highly polar, derivatization is not required but high-resolution chromatography is essential. Internal standards are recommended to ensure matrix correction and improve quantitation accuracy. The instruments below support these criteria and are validated for food safety and residue analysis under AOAC SMPR 2021.008.
