The European Standard method, EN-14105, 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 palmkernel oils due of the problem of peak overlapping. This method and ASTM D6584 are two of the most commonly used standardized analytical methods used for the analysis of biodiesel. 450-GC 多功能氣相色譜儀
