14C-SCAR

The University of Groningen (hereinafter: the UG) intends to acquire an optical radiocarbon analyser for the measurement of carbon-14, the C14-SCAR instrument. This instrument is required for research applications including the measurement of 14C in natural abundances, for 14C age determination ('dating'), accreditation of biomaterials and fuels, and for on-line measurements of atmospheric CO2 for anthropogenic greenhouse gas quantification. The UG requires an instrument that can measure ¹⁴C directly in gaseous CO₂ samples with the precision and sensitivity required for modern radiocarbon applications. The instrument must be suitable for automated laboratory workflows in which CO₂ produced from sample material can be fed directly into an analyser, and for atmospheric measurements at a field station. These requirements are essential for the intended research, as the use of gas-phase CO₂ …
