Infant formula and adult nutritionals. Determination of vitamin E and vitamin A by normal phase high performance liquid chromatography1 Scope This International Standard specifies a method for the simultaneous quantitative determination of vitamin E ( tocopherol and tocopheryl acetate) and vitamin A (13 cis and all trans isomers of retinyl palmitate and retinyl acetate) present in all forms of infant and adult formulas (powders, ready to feed liquids and liquid concentrates). Retinol is not used for fortification purposes and therefore is not addressed in this method. The innate
