A system of relatively low-cost but reliable components was assembled for time sharing a single analytical instrument in gas-exchange studies. Aside from an analytical instrument, recorder, gas standards and study vessels or compartments, only a simple assembly of timers, motor-driven cams, microswitches, gas solenoid valves and a single electronic relay were required. The system was developed for biological studies of photosynthesis and respiration, but can be readily adapted to air pollution and basic chemical problems.
