Abstract
Collaborative studies on the application of capillary gas-liquid chrom atography for the determination of trans unsaturated fatty acids are d escribed. The method investigated involves preparation of methyl ester s with methanolic potassium hydroxide followed by analysis of fatty ac id methyl esters by gas-liquid chromatography on polar capillary colum ns. Care has to be taken in selecting working conditions to obtain the best obtainable resolution of signals necessary for reliable identifi cation and determination of trans unsaturated fatty acids.
