Ammonium perfluorooctanoate (APFOA) acts as a surfactant in micellar electrokinetic chromatography, allowing for the effective separation of free unsaturated C18 fatty acids within 20 minutes.
The method uses a simple background electrolyte of 50 mM APFOA dissolved in a 90:10 water/methanol mixture at pH 10, with optimized conditions considering various factors such as solvent type and pH.
The study explores the unusual effectiveness of fluorocarbon micelles in separating hydrogenated long-chain fatty acids, analyzing aspects like micelle concentration, charge density, and mobility for a deeper understanding of the separation mechanism.

- Alexandre Wodrinski's research primarily focuses on the optimization and application of perfluorinated-micellar electrokinetic chromatography techniques for the separation of fatty acids.
- His recent article demonstrates the effective use of ammonium perfluorooctanoate (APFOA) as a surfactant, allowing for the repeatable and efficient separation of unsaturated C18 fatty acids in a short period of less than 20 minutes.
- The study emphasizes the importance of optimizing separation conditions, including factors such as organic solvent composition, counterion selection, APFOA concentration, and pH for enhanced chromatographic performance.
