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 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.

Key Learnings 

1. See how the SCION Instruments Biodiesel Analyzer is well suited to the analysis of free and total glycerol and mono, di and triglyceride content in biodiesel in accordance with EN14105. 
2. Understand the sample preparation conducted, and instrument parameters used to produce repeatable results indicating a suitable system performance for this application, compliant with EN14105.
