Abstract

We describe the design, construction, and testing of a new, simplified in situ radiocarbon extraction system at the University of Arizona. Blank levels for the new system are low ((234 ± 11) × 10³ atoms (1 σ; n = 7)) and stable. The precision of a given measurement depends on the concentration of ¹⁴C, but is typically <5% for concentrations of 100 × 10³ atoms g^-1 or more. The new system is relatively small and easy to construct, costs significantly less than the original in situ ¹⁴C extraction system at Arizona, and lends itself to future automation.
