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 one of the few 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, with the modification that we use an IR technology (Saturated Cavity Ringdown - SCAR) instead of one of the methods mentioned in the standard.

FAQ
FAQ
What is the carbon-14 method used for?
The carbon-14 method is used to measure how much of a material comes from renewable, bio-based sources. It is an essential method for companies wishing to demonstrate sustainability, comply with environmental legislation and obtain certification for bio-based materials. With C-14 analysis, companies can demonstrate that their products contain a high proportion of bio-based raw materials, thus reducing their carbon footprint.
What materials can be tested using the carbon-14 method?
The carbon-14 method can be used to analyse fuels, plastics and chemicals.
How does carbon-14 (C14) method work?
Carbon-14 analysis involves burning the sample and collecting the carbon dioxide (14C16O2). The carbon-14 content is then measured with extreme selectivity and sensitivity using an IR spectrometer (Saturated Cavity Ringdown - SCAR). This is done according to a modified version of ASTM D6866 to ensure the highest precision.
Why should I choose RISE for carbon-14 analysis?
We are one of few laboratories in Europe offering accredited carbon-14 analysis, which means that the analysis meets high quality standards and can be used to prove the use of renewable materials.
