Fig. 8From: A multiplexed gas exchange system for increased throughput of photosynthetic capacity measurementsFunctional schematic of OCTOflux system. Open semicircles represent atmospheric vent points. CO2 is injected into a stream of pressurized air, mixed in a buffering volume and distributed to eight chambers and a reference line. The return line of each chamber is either vented through its null line vent or directed through the IRGA sample cell using solenoid valvesBack to article page
