Analysis of biodiesel/FAME in diesel blends according to DIN EN 14078

To reduce the emission of greenhouse gases, regular fossil-based petrodiesel is blended with “biodiesel” in many countries. Chemically, biodiesel is FAME (fatty acid methyl esters), and its quantity in the diesel blend is tightly regulated and needs to be checked regularly. FTIR is an ideal tool to accurately quantify FAME content quickly without sample preparation.

Diesel containing biodiesel as a component has been sold in Europe for over 15 years. Biodiesel contains mainly FAME (fatty acid methyl esters) – the quantity of FAME which is allowed to be added is tightly regulated. The concentration needs to be monitored and checked several times when transported from a refinery or storage facility to the gas station. The check needs to be done quickly and accurately, without the need for laboratory work such as sample preparation. This is possible using Lyza 7000 FTIR spectrometer.
