	abstract = {Biobased content analysis is a well-established, analytically independent, standardized method to determine the biobased content of fuels and plastics, based on differences of the specific radiocarbon ( 14 C) activity of fossil and recent biogenic compounds. This biogenic content analysis can be useful for the producers as a quality assurance tool, for the customers as feedback about the truly biobased products and for the control organizations as an independent analytical tool to prove the biological origin. More than 100 commercially available foods, cosmetics, and drug samples have been used for biobased carbon content analysis by accelerator mass spectrometry (AMS) 14 C measurement to demonstrate the potential of this technique. Our results show that this measurement technique is a unique tool for the determination of biocontent in foodstuff and medical products. Most of the tested materials were nearly or completely biobased (≥ 98 pMC), and no completely fossil-based final product was detected. The lowest biogenic compound was measured in a vanilla aroma flavor. In 45 of the 102 samples selected a wide range (2–98%) presented fossil-based carbon content. The method can be applied for monitoring raw materials and final products for biobased content in the industry and consumer protection as well.},

	abstract = {The method of determining the biobased carbon content in liquid fuel samples is standardized, but
		different laboratories use different protocols during sample preparation and perform the measurements using
		different machines. The accelerator mass spectrometry (AMS) laboratories use different combustion, preparation,
		and graphitization methods for the graphite production for the spectrometric measurements. As a result, the
		intercomparison between the laboratories is inevitable to prove precision and accuracy and to demonstrate that the
		results are comparable. In this study, we present the results of an intercomparison campaign involving three 14C
		accelerator mass spectrometry laboratories. Five samples were used in the measurement campaign, including two
		biocomponents (fatty acid methyl ester, hydrotreated vegetable oil), one fossil component (fossil diesel), and two
		blends (mixtures of fossil and biocomponent with 90–10% mixing ratio) in the laboratories of CEDAD (Italy),
		ETH (Switzerland), and INTERACT (Hungary). The results presented by the laboratories are comparable, and all
		three laboratories could determine the biobased carbon content of the samples within 1% relative uncertainty,
		which is acceptable in the scientific, economic, and industrial fields for biocomponent determination.},
