- Аннотация: A new procedure was developed for the simultaneous determination of water- and fat-soluble vitamins by microemulsion electrokinetic chromatography. Using microemulsions based on sodium dodecyl sul-fate, Brij 35, 1-butanol, and heptane, 10 vitamins were separated (4 water-soluble and 6 fat-soluble) within 35 min. The efficiency of the separation was 800000 theoretical plates (effective capillary length, 40 cm). To enhance the selectivity, 2-propanol was used as a hydrophobizing addition into the microemulsion. The procedure was used for analyzing a kaolin-based vitamin premix. The use of microemulsion as an agent for extracting vitamins from the support considerably simplifies the sample preparation.
