- Аннотация: The influence of the pH and temperature of the mobile phase on the retention and separation of 14 vitamins and vitameric forms has been studied for four different stationary phases. The chromatographic conditions allowing the separation of 12 water-soluble vitamins and vitameric forms have been proposed. It has been established that the best separation of water-soluble vitamins can be achieved by employing gradient elution. The mobile phase A, (0.6% phosphoric acid) pH 1.5-1.8; mobile phase B, acetonitrile. For the separation of nicotinic and ascorbic acid it is preferable to use stationary phases Luna C18(2) and Gemini C18, while for the separation of riboflavin and riboflavin-5-phosphate the Synergy Hydro RP and Zorbaz SB-C18 stationary phases should be used. The selected conditions have been used for the determination of vitamins in commercial samples of vitamin preparations. The results are in good accordance with the producer data.
