Abstract

High-precision measurements of radiocarbon (14C) near or below a fraction modern 14C of one (F14C ≤ 1) are costly, requiring the shipment of samples to accelerator mass spectrometer (AMS) facilities that specialize in reporting rare isotope relative abundances. An accurate, ultra-sensitive linear absorption spectroscopy approach to detecting 14C would provide a simple and robust table-top alternative to off-site AMS facilities. Here we report the quantitative measurement of 14C in gas-phase samples of CO2 with F14C
