The tubes 50 may be any type of water transportable tube such as Nafion tubes made by PermaPure LLP of Toms River, N.J. Nafion tubes transport water across the membrane or tube wall through chemical reaction of the water with the Nafion material. The humidifier was then removed from the sample stream so that dry zero air could flow through the interior of the Nafion dryer, and the dryer was heated to 100C. This transfer is driven by the difference in water vapour pressure between the water . The tubes 50 will be filled with water from the water supply 14 under the action of gravity . The molecules of water are absorbed into the Naon Rtube walls and conveyed to dry gas ow. Nafion is also recommended to be used with water traps and hydrophobic filters that are included with all sampling devices. These instruments allow water to move through the Nafion membrane, gaining equilibrium of the partial pressure of water vapor on either side of the membrane. In the humidifier, the dry gas flows through a long coil of Nafion tubing submerged in heated water. 2. The water is absorbed into the walls of the Nafion tube and then is transferred as a vapor to a dry gas stream. Nafion is a material widely used in FC membranes; however, this paper studies a particular application of the material, Nafion tubing.
