Abstract

The water content in extra dry gases can be determined by
the condensation of water vapor on the cooled walls of the container.
After separation, vapor pressure is measured at room temperature
by the Pirani vacuummeter. In favorable conditions water
content as low as 1 μg per liter of gas at NTP can be detected.
