During the "Standards Development and International Harmonization: AOAC INTERNATIONAL Mid-Year Meeting" held on June 29, 2011, an Expert Review Panel (ERP) reviewed the method "Determination of Vitamin B12 in Infant Formula and Adult Nutritionals by HPLC." Under the new pathway to Official Methods, the ERP adopted the method as Official First Action. The method is applicable to the determination of vitamin B12 in infant formula and adult nutritionals. Data showed an average overall intermediate precision of 6.64% RSD, an estimated quantitation limit of 0.8 microg/kg, and a detection limit of 0.2 microg/kg in prepared samples. The standard range of the method is 2 to 200 microg/L, which corresponds to an analytical range of 0.8 to 500 microg/kg.
