Biodiesel: Determination of FAME Profile as a Measure of Purity

Biodiesel is produced around the world using a variety of biomass starting materials, including soy, canola oil, palm oil, distilled palm oil, and tallow. The biomass starting material used by a given manufacturing facility depends on how plentiful it is in their region of the world. It is important for bulk biodiesel producers to measure the FAME profile, as it is an indicator of the amount of useable fuel in the final B100 biodiesel product. DIN EN 14103 specifies a procedure for determining the FAME profile in B100 biodiesel samples.
