The test specimen is mounted in the diffusion cell, which is divided into a dry chamber and a controlled humidity chamber. A flow of dry nitrogen sweeps the dry side of the specimen, while the dry nitrogen carries the water vapor permeating through the specimen from the controlled humidity chamber to an infrared sensor. This sensor generates proportional electrical signals based on the water vapor concentration. The water vapor transmission rate is determined by analyzing and calculating these electrical signals. For package samples, dry nitrogen flows inside the package, while humidified nitrogen flows outside.

The pre-conditioned specimen is mounted in the gas diffusion cell to form a sealed barrier between two chambers. The lower-pressure chamber is first evacuated, followed by the evacuation of the entire cell. Gas is then introduced into the evacuated higher-pressure chamber, creating a constant pressure difference between the two chambers. The gas permeates through the specimen from the higher-pressure side to the lower-pressure side. By monitoring the pressure changes in the lower chamber, the gas permeability and other barrier properties of the specimen can be determined.
