ANALYSIS OF PHOSPHOLIPIDS IN LECITHINS - COMPARISON BETWEEN MICELLAR ELECTROKINETIC CHROMATOGRAPHY AND HIGH-PERFORMANCE LIQUID-CHROMATOGRAPHY

The determination of phospholipids in lecithins by HPLC and MEKC has b een compared. MEKC conditions have been optimized to provide a robust analytical method. MEKC offers the advantage of a much higher peak cap acity which results in an improved resolution, especially for phosphat idylserine. Although the repeatability of the MEKC data is somewhat lo wer than for HPLC, good quantitative results are obtained.
