A low-cost, portable system for the measurement of 14CO2 in gas streams

, : A low-cost, portable system for the measurement of 14CO2 in gas streams. Photosynthetica 7(4): 325-329

The construction of a portable solid-state instrument for the measurement of 14CO2 in gas streams, with adequate sensitivity for gas counting at levels of 14CO2 commonly used in translocation and photosynthesis experiments, is described.
