Measurement of carbon 14 (C 14)
There is currently a transition from fossil-based materials to products based on renewable materials. This transition has led to a need to control the proportion of a material that comes from renewable sources, i.e. is biogenic. We can offer C 14 / Carbon 14 analysis of various materials such as fuels, plastics and chemicals.
Purpose
As the only commercial laboratory in Europe, we have the opportunity to offer accredited C 14 analysis for determination of fossil / biogenic content. To measure a materials biobased content, the only general way is to measure the proportion of the sample's carbon consists of the isotope C 14, i.e. the ratio of the radioactive and stable isotopes of carbon. The method is also suitable for determining C-14 when isotope-labeled substances are used in tracer experiments, for example in studies of drug metabolism. In addition to the analysis service itself, we can also assist with guidance and problem solving.
Method
The sample is incinerated and the formed carbon dioxide is collected. The content of 14C16O2 is determined in an IR spectrometer with extreme sensitivity and selectivity.
The measurement is performed according to ASTM D6866-21, with the modification that we use an IR technology (Saturated Cavity Ringdown - SCAR) instead of one of the methods mentioned in the standard.
