摘要：
A method for the analysis of corn oil and free fatty acids in ethanol miscella was developed using gel permeation chromatography. Two Phenogel columns were connected in series to a refractive index detector and tetrahydrofuran was used as the mobile phase. Sample preparation involved only dilution with the mobile phase and filtration. Individual free fatty acids eluted as one peak. Reproducibility of the method was good with a relative standard deviation of 0.94-3.17%.
