The analyses of triglycerides on capillary columns is reported. Applications in which this technique can be used include: rapid identification of fats and oils, measurement of butter fat or coconut oil content in margarine or chocolate, monitoring of processes such as fractionation, transesterification or heat treatment. Although separation of all isomers within a group of triglycerides with identical carbon numbers is not usually feasible by gas chromatography (GC) alone, the resolution obtained with capillary columns gives more information than that obtained with packed column GC. The conditions used in this work are described. Persilylated columns coated with nonpolar gum phases could be used for ca. 1 yr with hundreds of injections.
