High-performance liquid chromatographic analysis of partial glycerides and other technical lipid mixtures.

A high-performance liquid chromatographic (HPLC) technique for the analysis of partial glyceride mixtures is described and some technical details are discussed. Gradient elution HPLC with a "moving-wire" detector linked to a computer is used for quantitative analysis. The method described has been applied to the analysis of mono-, di- and triglyceride mixtures, food emulsifiers, certain seed fats, and technical products such as polymer additives.
