Method Performance

Abstract The method for the “Determination of Vitamins D2 and D3 in Infant Formula and Adult Nutritionals by Ultra-Pressure Liquid Chromatography with Tandem Mass Spectrometry Detection (UPLC-MS/MS)” was adopted as AOAC Official First Action during the “Standards Development and International Harmonization: AOAC INTERNATIONAL Mid-Year Meeting” held June 29, 2011. During the meeting, an Expert Review Panel (ERP) evaluated the available validation information against standard method performance requirements (SMPRs) articulated by stakeholders. The method, approved by the ERP, is applicable for the determination of vitamin D (total vitamins D2 and D3). A range of products had been tested during a single-laboratory validation study. The products included butter, National Institute of Standards and Technology SRM 1849, eggs, cheese, yogurt, ready-to-eat cereal, bread, mushrooms, and tuna. The testing of the method established linearity in the range of 0.005–50 μg/mL. The recovery range was 93.4–100.9% for vitamin D2 and 102.4–106.2% for vitamin D3. The LOD and LOQ for vitamin D2 were reported as 0.20 and 0.61 μg/100 g, respectively; for vitamin D3, the reported values were 0.47 and 1.44 μg/100 g, respectively. The method met the SMPRs set by the Stakeholder Panel on Infant Formula and Adult Nutritionals (SPIFAN). It was, therefore, decided that the method was appropriate for Official First Action Method status.
