“…The water was pumped continuously from an intake in the ship's hull 2 to 3 m below the water surface, through the equilibrator, and then discarded. For Downwind Expedition the equilibrator was constructed after a design of Levine et al [1956]. For Monsoon Expedition a simpler design (Figure 1) similar to that of Takahashi [1961] was adopted.…”

“…Separations of gaseous constituents from liquid samples can be achieved by contacting the sample with a stream of nitrogen, thus making possible a gas phase analysis. Levine and associates (145) based a method for continuous measurement of dissolved oxygen in water on a Henry's law equilibrium between a flowing water sample and the oxygen content of a gas confined above it at constant pressure and volume. Gases have been separated semiautomatically by Hancher and Kammermeyer (110).…”

The high cost of quantitative analyses, together with the ever-increasing demand for more quantitative data both in laboratories and plants, has continued to accelerate the development of automatic methods. This review covers the two years which have elapsed since the last in this series (187, 188). Competition in electronic instruments for measuring physical properties has led to a sometimes bewildering array of choices in how best to solve a particular analytical problem. Perhaps the most significant developments during this time have been the wider use of the recently developed electronic tools such as spectrophotometers, refractometers, titrators, electronic balances, and radioactivity detectors. However, a much needed emphasis on new techniques of sampling (collecting, measuring, and treating) and of separation has also evolved.

“…Perhaps the most hopeful sign is the aw'akening interest in instrumentation as a means of recording w'aste properties or stream quality. Along with others, the Sanitary Engineering Center (14) is working tow'ard the development of a machine for continuously indicating and recording dissolved oxygen in surface water.
