Characteristic parameters in the measurement of 14C of biobased diesel fuels by liquid scintillation

• We analyse the direct method for the quantification of the amount of the biobased component in fuels.
• The minimum biobased component volume percent is studied.
• The best scintillation cocktail and the diesel/cocktail ratio have been obtained.

The direct method based on the radiocarbon content present in modern-day materials used for the quantification of the renewable origin component in diesel has been analysed in order to establish the best sample preparation and measuring conditions that minimise the limit of detection. The scintillation cocktail and the diesel/cocktail ratio have been optimised.
