A simple, compact, portable, and relatively durable instrument has been devised whereby the oxygen content of semimicro quantities of gases can be accurately and rapidly determined. A Beckman D‐2 oxygen analyzer is connected to a vacuum pump via a 3‐way valve in a way that the system can be evacuated. The evacuation process makes it possible to analyze a gas sample of less than 20 cc where 500‐ to 600‐cc were required by the unmodified analyzer. This unit was calibrated, using gases of known oxygen content. The results were very satisfactory and well within the limits of accuracy specified by the manufacturer.
