Separation of unsaturated fatty acids and related isomeric hydroperoxides by micellar electrokinetic chromatography

The separation of several unsaturated fatty acids and the isomeric hydroperoxides derived from them was examined by micellar electrokinetic chromatography. Uncharged polyoxyethylene lauryl ether (Brij 35) was used both as a surfactant and for dynamic coating. A mixed micelle of Brij 35 and SDS made...

Description
Summary:The separation of several unsaturated fatty acids and the isomeric hydroperoxides derived from them was examined by micellar electrokinetic chromatography. Uncharged polyoxyethylene lauryl ether (Brij 35) was used both as a surfactant and for dynamic coating. A mixed micelle of Brij 35 and SDS made it possible to separate oleic, linolenic acids and nearly all the isomeric hydroperoxides from these fatty acids in a single run in 15 min. The separation of arachidonic acid and the corresponding hydroperoxides was also possible.
