Introduction\"EN<\/a><\/h2>\n

The European Standard method, EN-14105<\/strong>, is used to determine the free glycerol and residual mono-, di- and triglyceride contents in fatty acid methyl esters (FAME) typically intended for addition to mineral oils. Total glycerol content is calculated from the results obtained. The method is suitable for FAME from rapeseed, sunflower and soybean oils, but is not suitable for FAME produced from or containing coconut and palm kernel oils due of the problem of peak overlapping. This method and ASTM D6584 are two of the most used standardized analytical methods used for the analysis of biodiesel.<\/p>\n

Experimental<\/h2>\n

The SCION Biodiesel analyser for EN 14105 is based on our 8300 GC platform, a cold-on-column injector, a SCION-Glycerides Inert Steel analytical column with a 2m retention gap and a High-Temp FID Detector. Analytical conditions for the EN 14105 analysis can be found in table 1.<\/p>\n\n\n\n\n\n\n\n\n\n

Sample Preparation<\/h2>\n

Calibration mixtures and internal standard solutions were prepared according to the method.100 mg of homogenized sample was accurately weighed in a 10 mL vial. Then, using a glass syringe, the following was added to the vial: 10\u03bcL of internal standard No. 1 stock solution, 100 \u03bcL of internal standard No. 2 stock solution and 100\u03bcL of MSTFA. Care was taken to ensure there was no contact with moisture. The vials were hermetically sealed and shaken vigorously. After storing the vials at room temperature for ~ 15 minutes, 8 mL of heptane was added to each. Then, 1 \u03bcL of the reaction mixture was automatically injected into the gas chromatograph according to the instrumental conditions described below (see Table 2 for typical results).<\/p>\n\n\n\n\n\n\n\n\n
