Abstract

A joint project was undertaken by the National Bureau of Standards (NBS) Atmospheric Chemistry Group and University of Arizona (UoA) Tandem Accelerator Mass Spectrometry Group to develop and evaluate accelerator **1**4C measurements of 50-1000 mu g carbon samples at a modest accuracy of 5-10%. Fe-C alloy targets prepared from standards and samples averaged 1. 6 mu A **1**2C** minus current. **1**4C measuremets yielded 5% precision and accuracy, limited by a blank equivalent to 11% modern carbon for targets containing approx. 100 mu g carbon. The contamination level was estimated to be approx. 15 mu g contemporary carbon (current atmospheric **1**4C). These results demonstrated that the Fe-C target is quite suitable for atmospheric and environmental studies that require measuring fossil/biogenic carbon in microgram samples.
