Description
Summary:According to the authors, the differences between label values and actual content of vitamins in dietary supplements have not been studied extensively. When the vitamin supplements were analyzed using the faster flow rate, however, the identification of some of the vitamins of interest could not be performed due to overlapping unidentified peaks from other ingrethents in the vitamins. Because of this, the flow rate was kept at 1.0 mL/min for analysis of the vitamin supplements.
