Abstract
A system is described for the precise continuous measurement of oxygen consumption and photo-synthetic oxygen evolution in a well defined light field with a polarographic oxygen electrode. The procedure uses a parallel light beam to irradiate samples, a relatively short pathlength and temperature regulation. Maximal sensitivity of the O2-mcasurement is 1.4 μmol O2/mV at 20°C. The O2-chamber and the O2-amplifier are presented in full detail together with a typical recorder tracing of a photosynthesis-irradiance curve.Keywords
