Vitamins Analysis by Capillary Electrophoresis

Vitamins are a series of trace compounds obtained from food that play important roles in human health. Vitamin analysis is essential for nutritional assessment and food production. A comprehensive overview of capillary electrophoresis for vitamins analysis is given. This chapter includes papers published since 1996 and can be seen as a guidance note of vitamins analysis using capillary electrophoresis. The analyses are discussed for water-soluble vitamins and fat-soluble vitamins according to different separation modes. In addition, various sample pretreatment methods avoiding matrix interferences with the analysis of vitamins are also described. Articles pertaining to different vitamins from a variety of food and beverages, dietary supplements, and pharmaceutical samples are included. This chapter highlights the unique performance of capillary electrophoresis for the qualitative analysis of vitamins in food.
