AOAC SPIFAN Stakeholder Panel Meeting Book (March 12, 2020)

Comparison - SPIFAN Previous & Present SLV Results

SLV/MLT = 97.6% – 107.2% for Adult Low Fat Powder = 96.2% – 103.5% for Infant Milk Powder = 92.9% – 100.8% for Infant Soy Powder

Conclusion: almost all analytes/matrices showed SLV vs. MLT agreement to within 5%

Conclusion

The method performed about as expected at First Source Laboratory running the SPIFAN materials, the SRM, and performing typical linearity and LOQ exercises Intermediate precision in the Indian matrices was very good and met SMPR requirements Accuracy (recovery) met criteria for all the elements in all products. For malt-based drinks studied, a special preparation of a direct weight of powder was needed. Method updates recommended: clarify what “high-purity” nitric acid means; add new sample prep
