The outlook on increasing costs for mineral oil makes regenerative energy sources more interesting. Biodiesel consists of Fatty Acid
Methyl Esters (FAME) produced by transesterification of natural oils e.g. rape oil. The quality control of biodiesel (DIN EN 14214)
implements the measurement of residual methanol, free glycerol and glycerol esters(mono-, di- and tri-glycerides). Methods and
maximum concentrations of the components are given in the standards DIN EN 14110 and DINEN 14105.
Shimadzu offers a complete method including sample preparation for the Quality Control of biodiesel with gas chromatography.
