The Haxo and Blinks electrode. A mathematical model.

Fick's diffusion equations have been solved for the Haxo and Blinks electrochemical determination of photosynthetic O(2) evolution. The model shows the method to be quantitative in the case of a "long" chamber measuring constant rates of O(2) evolution. Transients are amplitude distorted by an amount depending on the space distribution of the O(2) sources. A correction equation applied to the raw data permits the recovery of the original signal.
