Two independent programs have collected and analyzed atmospheric CO2 samples from Point Barrow, Alaska, for radiocarbon content (Δ14C) over the period 2003–2007. In one program, flask collection, stable isotope analysis, and CO2 extraction are performed by the Scripps Institution of Oceanography's CO2 Program and CO2 is graphitized and measured by accelerator mass spectrometry (AMS) at Lawrence Livermore National Laboratory. In the other program, the University of California, Irvine, performs flask collection, sample preparation, and AMS. Over 22 common sample dates spanning 5 yr, differences in measured Δ14C are consistent with the reported uncertainties and there is no significant bias between the programs.

Conversion Reaction

Abstract Using metallic zinc from BDH Chemicals, the conversion of water into hydrogen was investigated by measuring the D/H ratio of the latter. It was found that 8 μl of water, 3.0 g of zinc, and a reaction time of 30 minutes at 480 °C are the optimal conditions for the conversion reaction.
