Measurements of Dissolved Gases at Corps of Engineers Projects.

Abstract

Instruments to measure dissolved gases were tested and evaluated under field conditions. Limitations and potential problems with the various instruments were discussed and recommendations were made. For dissolved oxygen (DO) measurements, instruments that use polarographic probes were recommended. Chemical titration techniques were recommended for probe calibration and spot-checking polarographic probe readings. The D'Aoust Tensionometer and WES Saturometer were recommended for measurements to determine dissolved nitrogen (DN) concentrations. These techniques were recommended because they proved easy to use and were reasonably reliable under field conditions. Although it provided simultaneous determinations of DO and DN, gas chromatography was not recommended for field measurements. The instruments were too sensitive to field handling, and results were very operator dependent.
