Analysis of isomeric monoethylenic fatty acids in a partially hydrogenated herring oil by glass capillary gas liquid chromatography

The use of a glass capillary column coated with Silar 10 CP for gas liquid chromatographic analysis of geometric and positional isomers of monoethylenic fatty acids of a partially hydrogenated herring oil is reported. The results are in agreement with previous studies performed by different methods and demonstrate the usefulness of this technique in detecting and determining many types of isomeric fatty acids.
