AbstractAvailable techniques are reviewed for gas‐liquid chromatography of mono‐, di‐ and triglycerides and their chemical modification products. Major emphasis is placed upon optimum separation and quantitative estimation of the recorded peaks. Nonlinear rates of temp programming are shown to be superior to linear rates for maximum resolution of complex glyceride mixtures. The use of short columns improves the recoveries of the components but may not provide a sufficient number of theoretical plates for all types of separations. The quantitative interpretation of the results is facilitated by the utilization of a flame ionization detector which gives correct weight response for the combustible carbon content of these materials.
