An evaluation of trapping compounds used for determining14CO2 by liquid scintillation counting

  • A. Stewart

Four commonly used trapping agents for scintillation counting of14CO2 (Hyamine, Primene, ethanolamine and β-phenylethylamine) were assessed under identical conditions, the progress of trapping being measured directly by pressure changes and by liquid scintillation counting. It was found that quantitative absorption required considerably longer periods of time than those previously reported and that absorption at low14CO2 pressures was very slow. The effects of pressure and stirring rate were also studied.
