title: The use of a proprietary organic sample oxidiser to determine 14CO2 and 14C-carbonates of trace level specific radioactivity.
abstract: The specific radioactivity of 14CO2 (greater than 3 nCi mol-1) can be determined by conversion to an insoluble carbonate followed by re-evolution of the gas, using a mineral acid, through a proprietary organic sample oxidiser (Packard 306 Oxidiser, Packard Instruments Ltd, Caversham, Berks, U.K.).
