AOAC Method SMPR 2012.007 Instrumentation Guide

Standard Method Performance Requirements (SMPR) for Heavy Metals in a Variety of Foods and Beverages

AOAC SMPR 2012.007 outlines the minimum method performance requirements for determining total arsenic (As), cadmium (Cd), lead (Pb), and mercury (Hg) in food and beverage matrices, including infant formula, juices, rice products, and chocolate. Surveillance methods must achieve limits of quantitation (LOQs) of ≤10 ppb for general foods and ≤8 ppb for infant formula. Recovery must fall within 60–115% for concentrations between 8 ppb and 100 ppb, and 80–115% for concentrations above 100 ppb. Repeatability (RSDr) and reproducibility (RSDR) vary by range: RSDr must be ≤7.3%, and RSDR must be ≤32% for 8–100 ppb, ≤16% for 100 ppb–1 ppm, and ≤8% for 1–10 ppm.

The preferred analytical technique is inductively coupled plasma–mass spectrometry (ICP-MS), which provides the sensitivity and selectivity necessary for trace-level quantitation and interference control. Instruments must demonstrate robust analytical performance across diverse food matrices and analyte concentrations, ensuring accuracy and reproducibility between laboratories. Methods must incorporate internal quality controls, including blanks, check standards at low and mid-range concentrations, and use of certified reference materials (CRMs) when available. The systems listed below meet all performance criteria specified by AOAC SMPR 2012.007 when configured for regulated food and beverage surveillance workflows.
