Abstract: A multi-step process for measuring the biogenic contributions in the radiocarbon abundance of atmospheric volatile organic compounds (VOC) is described. It includes methods for isolating the total VOC fraction in whole air samples, for oxidizing this fraction to CO2 and for reducing the resulting CO2 to an AMS Fe-C target for 14C measurements. VOC fractions were separated from two composited urban tropospheric air samples collected in the summer of 1992 in Atlanta, GA.
