What is BS EN 14105 about?
BS EN 14105 specifies a method to determine the free glycerol and residual mono-, di- and triglyceride contents in fatty acid methyl esters (FAME). The total glycerol content is then calculated from the obtained results.
Under the conditions described, the quantification limits are 0,001 % (m/m) for free glycerol, 0,10 % (m/m) for all glycerides (mono-, di- and tri-). This method is suitable for FAME prepared from rapeseed, sunflower, soybean, palm, animal oils and fats and a mixture of them. It is not suitable for FAME produced from or containing coconut and palm kernel oils derivatives because of the overlapping of different glyceride peaks.
NOTE 1: For the purposes of this document, the term “% (m/m)” is used to represent the mass fraction.
NOTE 2: Under the common EN 14105 GC conditions squalene can coelute with alpha glycerol monostearate. If the presence of squalene is suspected, EN 17057 can be used to discriminate between squalene and glycerol monostearate.
Who is BS EN 14105 for?
BS EN 14105 on FAME is relevant to:
- Biodiesel industry
- Food technologists
- Biochemical engineers
- Automotive industry
Why should you use BS EN 14105?
FAME is typically intended for pure biodiesel or as a blending component for domestic and diesel fuels.
BS EN 14105 helps users by specifying a method to determine free glycerol and residual mono-, di- and triglyceride contents in FAME through the gas chromatology method.
Gas chromatology method is an analytical technique that separates sample mixture to determine free and total glycerol and mono-, di-, triglyceride contents in FAME.
The test methods in compliance with BS EN 14105, will enable you to accurately qualify and quantify the free and total glycerol and mono-, di-, triglyceride, for your specific application needs that require its addition to mineral oils.
What is changed since the last update?
