This chromatogram is an overlay of two injections: food industry FAME standard (black) and C19:0 methyl ester in toluene (red). An excellent separation of C19:0 (used in EN 14103 as an internal standard) and the most prevalent FAMEs found in biodiesel blends was achieved. Note that C4:0 from the food industry FAME standard elutes in the solvent front.
Printing tips! To print chromatograms full page, change the print settings in the print dialogue window of your PDF reader software: 1) "fit" or "fit to page", 2) "landscape" for wide chromatograms or "portrait" for tall chromatograms.
