A method is described for determining specific radioactivity and concentration of CO\* in blood, rumen fluid, and expired air. The CO2 of blood and rumen fluid samples is liberated selectively by 1 M phosphate buffer (pH 5.8) containing 1 mM NaN, and 5 mM NaF. Liberated CO2 is quantitatively trapped
A simple closed system for the serial determination of 14CO2 in small volumes of fluid samples, is described. The device consists of commercially available scintillation vials and silicone tube seals. 14CO2 is selectively liberated by citric acid and absorbed in a scintillation vial by Hyamine. Expe
