AOAC Method SMPR 2014.008 Instrumentation Guide

Standard Method Performance Requirements (SMPR) for Screening Method for Selected Adulterants in Dietary Ingredients and Supplements Containing Chondroitin Sulfate

AOAC SMPR 2014.008 outlines performance standards for qualitative screening methods used to detect adulterants in chondroitin sulfate-containing supplements. These include carrageenan, sodium alginate, sodium hexametaphosphate, propylene glycol alginate sulfate sodium, and other over-sulfated polysaccharides listed in Annex I. To comply, methods must detect each adulterant at or below 5% (w/w) with a minimum 90% probability of detection (POD) across all target compounds and matrix types. Methods must also achieve a false positive rate of 5% or less and provide 100% correct analysis of unadulterated (zero concentration) samples per matrix type. Validation requires at least 33 replicates at low-level concentration, five replicates at high-level, and five negative replicates per matrix, with a laboratory POD (LPOD) ≥ 0.95 and LPOD(0) ≤ 0.05. This screening process supports routine surveillance by trained technicians in supplement quality control environments.
