The Weiss saturometer, an instrument which measures dissolved gas tensions, was evaluated and compared with gas chromatographic apparatus. With vigorous shaking the saturometer equilibrated with dissolved gas tension only after fifteen to twenty‐five minutes in moderately supersaturated water. Paired analyses by gas chromatography and the saturometer did not differ significantly. Both methods (gas chromatography and the Weiss saturometer) appear to offer advantages in specific applications, and the method of choice for dissolved gas analysis remains dependent on individual requirements. The need for conscientious operation of the saturometer by an experienced operator was apparent.
