ANALYSIS OF IMPURITIES IN MODEL BIODIESEL USING ULTRAPERFORMANCE CONVERGENCE CHROMATOGRAPHY (UPC²).

The article focuses on a study for the analysis of acylglycerols and glycerol in a biodiesel model using ultra-performance convergence chromatography. The study employs pure fatty acid ethyl esters, glycerol and soybean oil. The study concludes that triacyl-glycerols, diacylglycerols, monoacylglycerols, and free glycerol ranging from 5.0 percent and 0.2 percent were easily separated from model biodiesel.
