抄録

Two kinds of carbon dioxide cylinders and three kinds of oxygen cylinders were got in market. Dew points of flowing gases from those cylinders were continuously measured by the photoelectric tube type dew-pointmeter, previously reported. And the following facts were recognized;<BR>1. Dew point of flowing gas rises as the flowing time goes on and the residual pressure of cylinder decreases.<BR>2. This rising tendency of dew point is steep at lower pressure.<BR>3. Dew point of some carbon dioxide below the specification of JIS may rise form -26°C at higher pressure to near 0°C at lower pressure and dew point of an ordinary oxygen form -33°C at higher pressure to near 0°C at lower pressure.<BR>4. Flowing gas from a dried cylinder has a small rising tendency of dew point as pressure decreases.<BR>5. On the case of carbon dioxide, this rising tendency of dew point begins just when liquid carbon dioxide vaporizes out and only gaseous phase occupies the volume of cylinder.
