A method for the continuous measurement of dissolved oxygen in water has been developed, based on establishing a Henry's law equilibrium between a flowing water sample and the oxygen content of a gas at constant pressure and volume. The results are not influenced by temperature, salt content, pollution, aeration constant, barometric pressure, or the dissolved nitrogen content of water.

effect (within the experimental accuracy) in determining yield. Similar results were obtained by Kuznetzov (7) with a Soxhlet type of extraction.
