摘要：

High-pressure liquid chromatography in the reversed-phase, ion-pairing mode has been used to determine ascorbic acid in foods and multivitamin products. While several counterions were investigated for utility, tridecylammonium formate was selected. Workup procedures are minimal, requiring only dissolution of the analyte in water. WIth detection at 254 nm, solutions of ascorbic acid of 0. 5 mg/100 ml can be determined.
