Analysis of α-Tocopherol Stereoisomers in Fortified Infant Formula by Chiral Chromatography.

An accurate and precise chiral chromatographic method for the analysis of isomeric forms of α-tocopherol is described. The method is able to distinguish between natural and synthetic tocopherol sources. The method is accurate and precise and is suitable either for routine product compliance testing during product manufacture or as a possible reference method.
