A method for direct resolution of conjugated trienoic fatty acid isomers by capillary electrophoresis has been developed. To obtain complete separation a dual cyclodextrin system was used. This contained heptakis-(6-sulfo)-beta-cyclodextrin (charged). Beta-cyclodextrin (uncharged) and sodium dodecylsulfate. Under optimized conditions, all seven isomers were well separated. On average, separation efficiency was 2.9 x 10(5) plates/m.
