Radiocarbon Detection / C14-SCAR for Environment
C14-SCAR for Environment
Emissions from fossil fuels can be tracked and quantified by measuring the ¹⁴C content of CO2 in air. The lower the content, the higher the contribution from combustion of fossil sources.
¹⁴CO2 monitoring around nuclear power plants and waste repositories can ensure safety from radioactive hazards to both workers of nuclear sites and the population living in their vicinity.
C14-SCAR fast measurement routines will provide a quasi-continous air monitoring capability, in combination with innovative automated atmospheric CO2 extraction process that are being developed by our partners.
Measurement process explained
C14-SCAR for environment is capable of continuously measuring the concentration of 14CO2 in air, the complete measurement process is divided into two steps:
1. CO2 accumulation and storage
An atmospheric sampler enables the direct extraction of CO2 gas from the air; the accumulated gas is sent to the sampler outlet as a stream of a mixture of CO2 and He (carrier gas).
2. Purification and measurement
The gas collected by the atmospheric sampler is trapped and purified inside C14-SCAR and transferred to the measuring cell.
When the measuring cell has been filled to the correct pressure, the Saturated CAvity Ring-down process begins and measurements are taken.
The analysis result is provided automatically after the measurement.
Performances
14C-SCAR is a very versatile instrument, it achieves excellent sensitivity at low measurement times, has a very wide dynamic range, about 4 decades, and requires a modest amount of sample to operate.
With measurement times in the order of 120min 14C-SCAR achieves sub-pmc accuracies.
