Abstract
An on-line respirometer and method for using the same is disclosed for determining the oxygen uptake of respiring samples. An overflow drain in the side portion of an enclosed reaction vessel is located to define an operational volume of slurry sample and headspace gases. The slurry sample is agitated using a mixer and/or a pump which recirculates the headspace gases through the slurry. Oxygen probes inserted into the headspace and the slurry sample determine the level of dissolved oxygen within the slurry sample and the headspace. The fixed ratio of available oxygen to oxygen demand is sufficient to measure the oxygen uptake directly, without the need for oxygen supplementation, for simple, fast and accurate analysis.
