AOAC Method SMPR 2019.003 Instrumentation Guide

Standard Method Performance Requirements (SMPR) for Quantitation of Cannabinoids in Hemp Plant Materials

AOAC SMPR 2019.003 outlines the method performance requirements for quantifying cannabinoids in plant materials derived from low-THC hemp varieties. The method must accurately measure cannabinoids such as CBD, CBDA, Δ9-THC, THCA, and others, all reported on a dry weight basis. Performance targets include a limit of quantitation (LOQ) of ≤ 0.05%, analytical ranges from 0.05–5% for most cannabinoids (up to 35% for CBD/CBDA), and recovery between 85–118% with precision (%RSDr) typically ranging from 2–5%. These criteria ensure consistent cannabinoid profiling and regulatory compliance across various hemp plant matrices.

Importantly, SMPR 2019.003 does not require a specific instrument type. As stated in the official document: “Any analytical technique(s) that measures the analytes of interest and meets the following method performance requirements is/are acceptable.” This includes validated methods based on LC-MS/MS, UHPLC-DAD, and other platforms. For example, AOAC Official Method 2018.11, a UHPLC-DAD method, has been validated to meet SMPR 2019.003. The instruments listed below are examples of LC-MS/MS systems that meet these requirements when used with validated workflows. However, laboratories may select any appropriate method or system that achieves the stated performance targets.
