Measurements of vapor uptake and release from thin films coated on the sensor can be conducted. A typical application for this module is to measure the swelling of polymer or cellulose films. The use of this saturated salt equilibrium vapor pressure chamber is a well-established and cost-effective method if compared to the use of a humidity generator in conjunction with e.g. standard flow module.
The sensor surface is separated from the liquid flow by a GORE-membrane* thereby creating an air-filled compartment over the sensor. Flowing saturated salt solutions over the membrane will generate a specific and controlled relative humidity in the volume above the sensor surface. The humidity above the sensor equilibrates almost instantly, enabling real-time measurements.
