Compliance with biodiesel quality standards requires accurate determination of total fatty acid methyl ester (FAME) content and linolenic acid methyl esters. This application note demonstrates the use of a GC‑FID method in accordance with EN 14103 for the analysis of B100 biodiesel, using a SCION gas chromatograph equipped with a split/splitless injector and a SCION‑WAXMS column. The method delivers reliable quantification across C14–C24 methyl esters with excellent repeatability.

Key learnings from this application note: 

1. Learn how to determine the total FAME and Linolenic Acid Methyl Esters in Biodiesel according to EN 14103 using a SCION Instruments analyser. 
2. Discover the excellent repeatability achieved using the SCION Instruments’ GC-FID. 
3. Understand how to calculate the FAME and Linolenic Acid content to fulfil the requirements specified in EN 14214.
